"Chinese style" as defined inInternet of Things (Internet of Things) refers to is the ubiquitous (Ubiquitous) terminal equipment (Devices) and facilities (Facilities), including with the "inner intelligence" sensors, mobile terminals, industrial systems, floor control system, the family of Intelligentfacilities, video surveillance systems, and external can "(Enabled), such as RFID, a variety of assets (the Assets), personal and vehicle carrying the wireless terminal" intelligent objects or animals "or" smart dust "(the Mote), through a variety of wireless and / or cable over long distances and / or short-range communication networks to achieve interoperability (M2M), application integration (the Grand Integration), and based on cloud computing, SaaS operation mode, in internal network (intranet), private network (extranet), and / or the Internet (Internet) environment, the use of appropriate information security mechanisms to provide a safe, controlled and even personalized real-time online monitoring, retrospective positioning, alarm linkage, command and control plan management, remote control, security, remote repair and maintenance, online upgrades, statistical reporting, decision support, the leadership of the desktop (showcase of the Cockpit Dashboard) management and service functions, "Everything," "efficient, energy saving, security environmental protection, "" possession, control, Camp integration [1].4.EU definitionIn September 2009, the Internet of Things and enterprise environments held in Beijing, China-EU Seminar on the European Commission and Social Media Division RFID Division is responsible for Dr. Lorent Ferderix, given the EU's definition of things: the Internet of Things is a dynamic global network infrastructure, it has a standards-based and interoperable communication protocols, self-organizing capabilities, including physical and virtual "objects" of identity, physical attributes, virtual features and smart interface and seamless integration of information networks .Internet of Things Internet and media, the Internet and business Internet one, constitute the future of the Internet.5.changeThe Internet of Things (Internet of Things) the word universally recognized at home and abroad Ashton, Professor of the MIT Auto-ID Center in 1999 first proposed to study RFID. The report of the same name released in 2005, the International Telecommunication Union (ITU), the definition and scope of the Internet of Things has been a change in the coverage of a larger expansion, no longer refers only to the Internet of Things based on RFID technology.Since August 2009, Premier Wen Jiabao put forward the "Experience China" Internet of Things was officially listed as a national one of the five emerging strategic industries, to write the "Government Work Report" Internet of Things in China has been the great concern of the society as a whole degree of concern is unparalleled in the United States, European Union, as well as other countries.The concept of Internet of Things is not so much a foreign concept, as it has been the concept of a "Made in China", his coverage of the times, has gone beyond the scope of the 1999 Ashton professor and the 2005 ITU report referred to, Internet of Things has been labeled a "Chinese style" label.6.BackgroundThe concept of Internet of Things in 1999. Internet-based, RFID technology and EPC standards, on the basis of the computer Internet, the use of radio frequency identification technology, wireless data communication technology, a global items of information to real-time sharing of the physical Internet "Internet of things" (referred to as the Internet of Things) , which is also the basis of the first round of the China Internet of Things boom set off in 2003.The sensor network is built up based on sensing technology network. Chinese Academy of Sciences in 1999 on the start sensor network research and has made some achievements in scientific research, the establishment of applicable sensor network.1999, held in the United States, mobile computing and networking International Conference, "The sensor network is a development opportunity facing humanity in the next century. In 2003, the United States, "Technology Review" proposed sensor network technology will be future changes ten people's lives first.November 17, 2005, the WSIS held in Tunis (WSIS), the International TelecommunicationUnion released ITU Internet Report 2005: Internet of Things ", citing the concept of the" Internet of things ". The report pointed out that the ubiquitous "Internet of Things" communication era is approaching, all the objects in the world, from tires to toothbrushes, from housing to the tissue via the Internet, take the initiative to be exchanged. Radio Frequency Identification (RFID), sensor technology, nanotechnology, intelligent embedded technology will be more widely used.According to the description of the ITU, the era of things, a short-range mobile transceivers embedded in a variety of daily necessities, human beings in the world of information and communication will receive a new communication dimension, from any time communication between people of the place of connection extended to the communication connection between persons and things and things and things. The Internet of Things concept of the rise, largely due to the International Telecommunication Union (ITU), the title of Internet of Things 2005 annual Internet Report. However, the ITU report the lack of a clear definition of Things.Domestic Internet of Things is also there is no single standard definition, but the Internet of Things In essence, the Internet of Things is a polymer application of modern information technology to a certain stage of development and technological upgrading of various sensing technology modern network technology and artificial intelligence and automation technology aggregation and integration of applications, so that the human and material wisdom of dialogue to create a world of wisdom. Because the development of the Internet of Things technology, involving almost all aspects of IT, innovative application and development of a polymer, systematic, and therefore be called revolutionary innovation of information industry. Summed up the nature of the Internet of Things is mainly reflected in three aspects: First, the Internet features that need to be networked objects must be able to achieve the interoperability of the Internet; identification and communication features, that is included in the Internet of Things "objects" must to have the functions of automatic identification and physical objects communication (M2M); intelligent features, the network system should have automated, self-feedback and intelligent control features January 28, 2009, Obama became the President of the United States, held with U.S. business leaders a "round table", as one of the only two representatives, IBM CEO Sam Palmisano for the first time that "the wisdom of the Earth" this concept, it is recommended that the new government to invest in a new generation of intelligent infrastructure.February 24, 2009 news, IBM Greater China CEO money crowd called "Smarter Planet"strategy announced in the forum 2009IBM.This concept was put forth, that is the great concern of the United States from all walks of life, and even analysts believe that IBM's vision is very likely to rise to U.S. national strategy, and caused a sensation in the world. IBM believes that the industry, the next phase of the mission is to make full use of the new generation of IT technology in all walks of life among specifically, is the embedded sensors and equipment to the power grid, railways, bridges, tunnels, highways, buildings, water supply systems dams, oil and gas pipelines and other objects, and is generally connected to the formation of Things.Strategy conference, IBM, and implant the concept of "wisdom" in the implementation of the infrastructure, strong, not only in the short term to stimulate the economy, promote employment, and in a short period of time for China to build a mature wisdom infrastructure platform.IBM "Smarter Planet" strategy will set off again after the wave of Internet technology industrial revolution. Former IBM CEO Lou Gerstner has raised an important point of view, every 15 years, a revolution in computing model. This judgment is the same as Moore's Law accurately call it a "15-year cycle Law". Before and after 1965, changes to the mainframe as a symbol, 1980 marked by the popularization of personal computers, 1995, the Internet revolution. Each such technological change are caused by the enterprise, industry and even the national competitive landscape of major upheaval and change. To a certain extent in the Internet revolution is ripening by the "information superhighway" strategy. 1990s, the Clinton administration plan for 20 years, $ 200 billion to -4000 billion, construction of the U.S. National Information Infrastructure, to create a huge economic and social benefits.Today, the "Smarter Planet" strategy by many Americans that there are many similarities with the "information superhighway", the same they revive the economy, a key strategy for competitive advantage. The strategy can be set off, not only for the United States, such as the Internet revolution was the wave of technological and economic concern, more attention from the world."Internet of Things prospects are very bright, it will dramatically change our current way of life." Demonstration director of the Center of Nanjing University of Aeronautics and Astronautics, National Electrical and Electronic Zhao Guoan said. Industry experts said that the Internet of things to our life personification of the things became a kind of human.Goods (goods) in the world of physical objects associated with each other "exchange", without the need for human intervention.The Internet of Things using radio frequency identification (RFID) technology, to achieve the interconnection and sharing of the automatic identification of goods (products) and information through the computer Internet. It can be said that the Internet of Things depict the world is full of intelligent. In the world of Internet of Things, material objects connected to the dragnet.The second session, held at Peking University in November 2008, China Mobile Government Seminar "Knowledge Society and Innovation 2.0", the experts made the mobile technology, the Internet of Things technology led to the development of economic and social form, innovative forms of change, and promote the The next generation of innovation for the knowledge society as the core of user experience (innovative 2.0) the formation of innovation and development of the form to pay more attention to the user to focus on people-oriented. Research institutions is expected to 10 years, the Internet of Things may be mass adoption of this technology will develop into one of thousands of yuan-scale high-tech market, the industry than the Internet 30 times.It is learned that the things industry chain can be broken down into the identity, perception, processing and information transfer, four links, each link of the key technologies for the wireless transmission network of RFID, sensors, smart chip and telecom operators. EPOSS in the "Internet of Things in 2020" report, an analysis predicted that the future development of the Internet of Things will go through four stages, 2010, RFID is widely used in the field of logistics, retail and pharmaceutical objects interconnect 2010 to 2015, 2015 ~ In 2020, the object into the semi-intelligent, intelligent objects into 2020.As the vanguard of the Internet of Things, RFID has become the most concerned about the technology market. The data show that the global RFID market size in 2008 from $ 4.93 billion in 2007 rose to $ 5.29 billion, this figure covers all aspects of the RFID market, including tags, readers and other infrastructure, software and services. RFID card and card-related infrastructure will account for 57.3 percent of the market, reaching $ 3.03 billion. Application from financial and security industries will drive the market growth of RFID cards. Analysys International forecasts, the Chinese RFID market size in 2009 will reach 5.0 billion, a CAGR of 33%, in which the electronic tag is more than 3.8 billion yuan, the reader close to 700 million yuan, software and services market to reach 500 million yuan pattern.MEMS is the abbreviation of the micro-electromechanical systems, MEMS technology is built on the basis of micro / nano, the market prospect is broad. The main advantage of the MEMS sensoris the small size, large-scale mass production cost reduction, mainly used in two major areas of automotive and consumer electronics. Under ICInsight the latest report is expected in 2007-2012, global sales of semiconductor sensors and actuators based on MEMS will reach 19 percent compound annual growth rate (CAGR), compared with $ 4.1 billion in 2007 to five years will achieve $ 9.7 billion in annual sales.7.PrincipleInternet of Things is on the basis of the computer Internet, RFID, wireless data communications technology, to construct a cover everything in the world's "Internet of Things". In this network, the goods (products) to each other "exchange", without the need for human intervention. Its essence is the use of radio frequency identification (RFID) technology to achieve the interconnection and sharing of the automatic identification of goods (products) and information through the computer Internet.The Internet of Things is a very important technology is radio frequency identification (RFID) technology. RFID is radio frequency identification (Radio Frequency Identification) technology abbreviation, is an automatic identification technology in the 1990s began to rise, the more advanced a non-contact identification technology. The development of RFID technology based on a simple RFID system, combined with existing network technology, database technology, middleware technology, to build a one composed by a large number of networked readers and numerous mobile label, much larger than the Internet of Things trend.RFID, It is able to let items "speak" a technique. In the "Internet of Things" concept, RFID tags are stored in the specification and interoperability information collected automatically by wireless data communications network to a central information system, to achieve the identification of goods (products), and then through the open computer network for information exchange and sharing, items "transparent" management.The information technology revolution in the Internet of Things is referred to as IT mobile Pan of a specific application. Internet of Things through IntelliSense, identification technology and pervasive computing, ubiquitous network convergence applications, breaking the conventional thinking before, human beings can achieve ubiquitous computing and network connectivity [3]. The traditional thinking has been the separation of physical infrastructure and IT infrastructure: on the one hand, airports, roads, buildings, while on the other hand, the data center, PC, broadband. In theera of the "Internet of Things", reinforced concrete, cable with the chip, broadband integration into a unified infrastructure, in this sense, the infrastructure is more like a new site of the Earth, the world really works it, which including economic management, production operation, social and even personal life. "Internet of Things" makes it much more refined and dynamic management of production and life, to manage the future of the city to achieve the status of "wisdom" to improve resource utilization and productivity levels, and improve the relationship between man and nature. 8.Agency1, institution-buildingAs the first national Internet of Things industry community organizations - the application of professional Committee of China Electronic Chamber of Things technology products (referred to as: "objects of the IPCC"), the Ministry of Civil Affairs in June 2010, preliminary approved by the Ministry of August being reported that the Ministry of Civil Affairs for final approval.2, the main taskServe as a bridge between business and government to assist the Government of the industry guidance, coordination, consultation and services to help members to reflect the business requirements to the Government; coordinate the relationship between enterprises to strengthen technical cooperation, product distribution, the elimination of vicious competition ; supervision of members the correct implementation of national laws and regulations, to regulate the industry; member of information communication technology products, cooperation, resource sharing, capital operation, and promote the application of Internet of Things technologies and products, and promote the Internet of Things industrial scale , co-development.9.ConstructionInternet of Things in the practical application to carry out requires the involvement of all walks of life, and need the guidance of the national government as well as related regulations and policies to assist the launching of the Internet of Things has the scale, broad participation, management, technical, and material properties, etc. other features, the technical problem is the most crucial issues of Things billion Bo logistics consulting, Internet of Things technology is an integrated technology, a system not yet which company has overall responsibility for network planning and construction of the entire system, theoretical studies have commenced in all walks of life and the practical application is limited to within the industry. The key is on the planning and design andresearch and development of the Internet of Things research in the field of RFID, sensors, embedded software, and transmission of data calculation. In general, to carry out the steps of the Internet of things mainly as follows:(1) identified the object attributes, properties, including static and dynamic properties of the static property can be stored directly in the label, the dynamic properties need to start with sensors to detect real-time;(2) the need to identify the equipment to complete the reading of object attributes, and information into a data format suitable for network transmission;(3) the object of information transmitted over the network to the information processing center (processing center may be distributed, such as home computers or mobile phones, may also be centralized, such as China Mobile IDC) by the processing center to complete the object communication calculation.10.key areasInternet of Things 4 key areas:(1) RFID;(2) sensor network;(3) The M2M;(4) integration of the two.11.TrendIndustry experts believe that the Internet of things on the one hand can improve economic efficiency and significant cost savings; the other hand, can provide technical impetus to global economic recovery. Currently, the United States, the European Union are all invested heavily in-depth study to explore the Internet of Things. The country is also highly concerned about the emphasis of Things, Industry and Information Technology Ministry in conjunction with the relevant departments are conducting research in a new generation of IT to the formation of policies and measures to support the development of a new generation of IT.China Mobile CEO Wang Jianzhou has repeatedly mentioned the Internet of Things will become the focus of future development of China Mobile. He will be invited to Taiwan to produce RFID, sensors and bar code manufacturers and China Mobile. According to him, the use of the Internet of Things technology, Shanghai Mobile has a number of industrial customers tailor the datacollection, transmission, processing and business management in one set of wireless application solutions. The latest data show that Shanghai Mobile has more than 100,000 chips mounted on a taxi, bus, various forms of matter networking applications in all walks of prowess, to ensure the orderly operation of the city. During the Shanghai World Expo, "the bus services through" will be fully applied to the Shanghai public transport system, the smooth flow traffic to the most advanced technology to protect Expo area; for logistics transportation management, e-logistics ", will provide users with real-time accurate information of Cargo, vehicle tracking and positioning, the transport path selection, logistics network design and optimization services greatly enhance the comprehensive competitiveness of logistics enterprises.In addition, the popularization of the "Internet of Things" for the number of animals, plants and machinery, sensors and RFID tags of items and related interface devices will greatly exceed the number of mobile phones. The promotion of the Internet of Things will become a drive to promote economic development for the industry to open up a potential development opportunities. According to the current demand on the Internet of Things, in recent years, billions of sensors and electronic tags, which will greatly promote the production of IT components, while increasing the number of job opportunities.According to reports, it is necessary to truly build an effective Internet of things, there are two important factors. First, the scale, only with the scale to make the items of intelligence play a role. For example, a city of one million vehicles, if we only 10000 vehicles installed on the smart system, it is impossible to form an intelligent transportation system; two mobility items are usually not static, but in the state of the movement , we must maintain the items in the state of motion, and even high-speed motion state can at any time for dialogue.FORRESTER of the authority of the U.S. advisory body predicted that 2020, the world of business of the Internet of Things, compared with the business of interpersonal communication, will reach 30 to 1, so the "Internet of Things" is known to be the next one trillion communications services.Internet of Things heat wave Why is rapidly growing in China? Internet of Things in China rapid rise thanks to the several advantages of our country in terms of things.In the early 1999 launched the Internet of Things core sensor network technology research, R & D level in the world; the second, sensor network field in the world, China is the standard one ofthe dominant country, the patent owner; third China is one of the countries to achieve a complete industrial chain of Things; Fourth, China's wireless communications network and broadband coverage provides a solid infrastructure to support the development of the Internet of Things; Fifth, China has become the world's first the three major economies, with strong economic strength to support the development of the Internet of Things.12.MythThe current understanding of the Internet of things there are a lot of misunderstanding, which is also a direct impact on our understanding of Things on the development of the logistics industry, it is necessary first to distinguish errors, clarify our thinking.One sensor networks or RFID network equivalent of Things. The fact that sensor technology, or RFID technology, or are simply one of the information collection technology. In addition to the sensor technology and RFID technology, GPS, video recognition, infrared, laser, scanning can be achieved automatically identify physical objects to communicate technical information collection technology can become the Internet of Things. Sensor networks or RFID network is just an application of Things, but not all of Things.Second, the Internet of Things as a myriad of unlimited extension of the Internet of Things as a completely open for all things, all of the interconnections, all shared Internet platform.In fact, the Internet of Things is not simple infinite extension of the global sharing of the Internet. Even if the Internet is also not only refers to we typically think of the international sharing computer network, Internet, WAN and LAN. Internet of Things can be both an extension of our usual sense of the Internet to the matter; LAN, professional can also be based on real needs and industrial applications. The reality is not necessary and can not make all the items networking; no need to make professional, LAN must be connected to the global Internet sharing platform. Of things in the future the Internet will be very different from the professional network of similar smart logistics, smart transportation, smart grid; the intelligence community and other local area network is the largest use of space.Ter, that the ubiquitous network of the Internet of Things Internet of Things, and therefore the Internet of Things is a castle in the air, is difficult to achieve the technology. In fact the Internet of things are real, many of the primary Internet of Things applications already for our services. The Internet of Things concept is introduced in many real-world applications based on polymericintegrated innovation, pre-existing network with the Internet of Things, intelligent, automated system, summarized and upgrading it upgraded from a higher perspective our knowledge.Four of Things as a basket, and everything installed inside; based on self-awareness, and only be able to interact, communication products as the Internet of Things applications. For example, just embedded some of the sensors, to become the so-called Internet of Things appliances; products labeled with RFID tags, became the Internet of Things applications.esThings widely used throughout the intelligent transportation, environmental protection, government, public safety, peace at home, smart fire, industrial monitoring, environmental monitoring, elderly care, personal health, floriculture, water monitoring, food traceability, enemy detection and intelligence collection and other fields.International Telecommunication Union in 2005, a report has portrayed the picture of the era of the "Internet of Things": car when the driver operational errors will automatically alarm; briefcase will remind the owner forgot something; clothes will "tell" washing machine color and water temperature requirements. Billion Bo logistics consulting vivid introduction of Things in the logistics field, for example, a logistics company, application of Things truck, when loading overweight, the car will automatically tell you overloaded and overload how many, but the space remaining , the severity of goods with how to tell you; when handling staff unloading a cargo packaging may be shouting "throw you hurt me", or "My dear, you do not get too barbaric, you can?"; when the driver and others gossip, trucks will pretend boss's voice roaring "stupid, the grid!Internet of things to make full use of a new generation of IT technology in all walks of life among, specifically, is embedded sensors and equipment to the power grid, railways, bridges, tunnels, highways, buildings, water systems, dams, oil and gas pipelines, etc.kinds of objects, and then "Internet of Things" with the existing Internet to integrate and realize the integration of human society and the physical system, which in this integrated network, there is the ability to super-powerful central computer cluster, integrated network staff implementation of real-time management and control of the machinery, equipment and infrastructure, on this basis, the human can be more refined and dynamic management of production and life, to achieve the status of the "wisdom", to improve resource utilization and productivity levels, and improve human the relationship between the natural.。
物联网常用术语在当今数字化的时代,物联网(Internet of Things,简称 IoT)正以惊人的速度改变着我们的生活和工作方式。
从智能家居到工业自动化,从智能交通到医疗保健,物联网的应用无处不在。
然而,要理解物联网的世界,首先需要熟悉一些常用的术语。
一、传感器(Sensor)传感器是物联网系统中获取信息的关键组件。
它能够感知环境中的物理量,如温度、湿度、压力、光照、声音等,并将这些物理量转换为电信号或数字信号,以便后续的处理和传输。
例如,在智能家居中,温度传感器可以实时监测室内温度,当温度过高或过低时,自动启动空调或暖气系统进行调节。
二、执行器(Actuator)与传感器相反,执行器是根据接收到的指令来执行动作的设备。
常见的执行器包括电机、阀门、继电器等。
例如,在智能灌溉系统中,当土壤湿度传感器检测到土壤湿度低于设定值时,控制器会向灌溉阀门的执行器发送指令,打开阀门进行灌溉。
三、物联网网关(IoT Gateway)物联网网关是连接物联网设备和云平台的桥梁。

The report of the same name released in 2005, the International Telecommunication Union (ITU), the definition and scope of the Internet of Things has been a change in the coverage of a larger expansion, no longer refers only to the Internet of Things based on RFID technology.Since August 2009, Premier Wen Jiabao put forward the "Experience China" Internet of Things was officially listed as a national one of the five emerging strategic industries, to write the "Government Work Report" Internet of Things in China has been the great concern of the society as a whole degree of concern is unparalleled in the United States, European Union, as well as other countries.The concept of Internet of Things is not so much a foreign concept, as it has been the concept of a "Made in China", his coverage of the times, has gone beyond the scope of the 1999 Ashton professor and the 2005 ITU report referred to, Internet of Things has been labeled a "Chinese style" label.6.BackgroundThe concept of Internet of Things in 1999. Internet-based, RFID technology and EPC standards, on the basis of the computer Internet, the use of radio frequency identification technology, wireless data communication technology, a global items of information to real-time sharing of the physical Internet "Internet of things" (referred to as the Internet of Things) , which is also the basis of the first round of the China Internet of Things boom set off in 2003.The sensor network is built up based on sensing technology network. Chinese Academy of Sciences in 1999 on the start sensor network research and has made some achievements in scientific research, the establishment of applicable sensor network.1999, held in the United States, mobile computing and networking International Conference, "The sensor network is a development opportunity facing humanity in the next century. In 2003, the United States, "Technology Review" proposed sensor network technology will be future changes ten people's lives first.November 17, 2005, the WSIS held in Tunis (WSIS), the International TelecommunicationUnion released ITU Internet Report 2005: Internet of Things ", citing the concept of the" Internet of things ". The report pointed out that the ubiquitous "Internet of Things" communication era is approaching, all the objects in the world, from tires to toothbrushes, from housing to the tissue via the Internet, take the initiative to be exchanged. Radio Frequency Identification (RFID), sensor technology, nanotechnology, intelligent embedded technology will be more widely used.According to the description of the ITU, the era of things, a short-range mobile transceivers embedded in a variety of daily necessities, human beings in the world of information and communication will receive a new communication dimension, from any time communication between people of the place of connection extended to the communication connection between persons and things and things and things. The Internet of Things concept of the rise, largely due to the International Telecommunication Union (ITU), the title of Internet of Things 2005 annual Internet Report. However, the ITU report the lack of a clear definition of Things.Domestic Internet of Things is also there is no single standard definition, but the Internet of Things In essence, the Internet of Things is a polymer application of modern information technology to a certain stage of development and technological upgrading of various sensing technology modern network technology and artificial intelligence and automation technology aggregation and integration of applications, so that the human and material wisdom of dialogue to create a world of wisdom. Because the development of the Internet of Things technology, involving almost all aspects of IT, innovative application and development of a polymer, systematic, and therefore be called revolutionary innovation of information industry. Summed up the nature of the Internet of Things is mainly reflected in three aspects: First, the Internet features that need to be networked objects must be able to achieve the interoperability of the Internet; identification and communication features, that is included in the Internet of Things "objects" must to have the functions of automatic identification and physical objects communication (M2M); intelligent features, the network system should have automated, self-feedback and intelligent control features January 28, 2009, Obama became the President of the United States, held with U.S. business leaders a "round table", as one of the only two representatives, IBM CEO Sam Palmisano for the first time that "the wisdom of the Earth" this concept, it is recommended that the new government to invest in a new generation of intelligent infrastructure.February 24, 2009 news, IBM Greater China CEO money crowd called "Smarter Planet"strategy announced in the forum 2009IBM.This concept was put forth, that is the great concern of the United States from all walks of life, and even analysts believe that IBM's vision is very likely to rise to U.S. national strategy, and caused a sensation in the world. IBM believes that the industry, the next phase of the mission is to make full use of the new generation of IT technology in all walks of life among specifically, is the embedded sensors and equipment to the power grid, railways, bridges, tunnels, highways, buildings, water supply systems dams, oil and gas pipelines and other objects, and is generally connected to the formation of Things.Strategy conference, IBM, and implant the concept of "wisdom" in the implementation of the infrastructure, strong, not only in the short term to stimulate the economy, promote employment, and in a short period of time for China to build a mature wisdom infrastructure platform.IBM "Smarter Planet" strategy will set off again after the wave of Internet technology industrial revolution. Former IBM CEO Lou Gerstner has raised an important point of view, every 15 years, a revolution in computing model. This judgment is the same as Moore's Law accurately call it a "15-year cycle Law". Before and after 1965, changes to the mainframe as a symbol, 1980 marked by the popularization of personal computers, 1995, the Internet revolution. Each such technological change are caused by the enterprise, industry and even the national competitive landscape of major upheaval and change. To a certain extent in the Internet revolution is ripening by the "information superhighway" strategy. 1990s, the Clinton administration plan for 20 years, $ 200 billion to -4000 billion, construction of the U.S. National Information Infrastructure, to create a huge economic and social benefits.Today, the "Smarter Planet" strategy by many Americans that there are many similarities with the "information superhighway", the same they revive the economy, a key strategy for competitive advantage. The strategy can be set off, not only for the United States, such as the Internet revolution was the wave of technological and economic concern, more attention from the world."Internet of Things prospects are very bright, it will dramatically change our current way of life." Demonstration director of the Center of Nanjing University of Aeronautics and Astronautics, National Electrical and Electronic Zhao Guoan said. Industry experts said that the Internet of things to our life personification of the things became a kind of human.Goods (goods) in the world of physical objects associated with each other "exchange", without the need for human intervention.The Internet of Things using radio frequency identification (RFID) technology, to achieve the interconnection and sharing of the automatic identification of goods (products) and information through the computer Internet. It can be said that the Internet of Things depict the world is full of intelligent. In the world of Internet of Things, material objects connected to the dragnet.The second session, held at Peking University in November 2008, China Mobile Government Seminar "Knowledge Society and Innovation 2.0", the experts made the mobile technology, the Internet of Things technology led to the development of economic and social form, innovative forms of change, and promote the The next generation of innovation for the knowledge society as the core of user experience (innovative 2.0) the formation of innovation and development of the form to pay more attention to the user to focus on people-oriented. Research institutions is expected to 10 years, the Internet of Things may be mass adoption of this technology will develop into one of thousands of yuan-scale high-tech market, the industry than the Internet 30 times.It is learned that the things industry chain can be broken down into the identity, perception, processing and information transfer, four links, each link of the key technologies for the wireless transmission network of RFID, sensors, smart chip and telecom operators. EPOSS in the "Internet of Things in 2020" report, an analysis predicted that the future development of the Internet of Things will go through four stages, 2010, RFID is widely used in the field of logistics, retail and pharmaceutical objects interconnect 2010 to 2015, 2015 ~ In 2020, the object into the semi-intelligent, intelligent objects into 2020.As the vanguard of the Internet of Things, RFID has become the most concerned about the technology market. The data show that the global RFID market size in 2008 from $ 4.93 billion in 2007 rose to $ 5.29 billion, this figure covers all aspects of the RFID market, including tags, readers and other infrastructure, software and services. RFID card and card-related infrastructure will account for 57.3 percent of the market, reaching $ 3.03 billion. Application from financial and security industries will drive the market growth of RFID cards. Analysys International forecasts, the Chinese RFID market size in 2009 will reach 5.0 billion, a CAGR of 33%, in which the electronic tag is more than 3.8 billion yuan, the reader close to 700 million yuan, software and services market to reach 500 million yuan pattern.MEMS is the abbreviation of the micro-electromechanical systems, MEMS technology is built on the basis of micro / nano, the market prospect is broad. The main advantage of the MEMS sensoris the small size, large-scale mass production cost reduction, mainly used in two major areas of automotive and consumer electronics. Under ICInsight the latest report is expected in 2007-2012, global sales of semiconductor sensors and actuators based on MEMS will reach 19 percent compound annual growth rate (CAGR), compared with $ 4.1 billion in 2007 to five years will achieve $ 9.7 billion in annual sales.7.PrincipleInternet of Things is on the basis of the computer Internet, RFID, wireless data communications technology, to construct a cover everything in the world's "Internet of Things". In this network, the goods (products) to each other "exchange", without the need for human intervention. Its essence is the use of radio frequency identification (RFID) technology to achieve the interconnection and sharing of the automatic identification of goods (products) and information through the computer Internet.The Internet of Things is a very important technology is radio frequency identification (RFID) technology. RFID is radio frequency identification (Radio Frequency Identification) technology abbreviation, is an automatic identification technology in the 1990s began to rise, the more advanced a non-contact identification technology. The development of RFID technology based on a simple RFID system, combined with existing network technology, database technology, middleware technology, to build a one composed by a large number of networked readers and numerous mobile label, much larger than the Internet of Things trend.RFID, It is able to let items "speak" a technique. In the "Internet of Things" concept, RFID tags are stored in the specification and interoperability information collected automatically by wireless data communications network to a central information system, to achieve the identification of goods (products), and then through the open computer network for information exchange and sharing, items "transparent" management.The information technology revolution in the Internet of Things is referred to as IT mobile Pan of a specific application. Internet of Things through IntelliSense, identification technology and pervasive computing, ubiquitous network convergence applications, breaking the conventional thinking before, human beings can achieve ubiquitous computing and network connectivity [3]. The traditional thinking has been the separation of physical infrastructure and IT infrastructure: on the one hand, airports, roads, buildings, while on the other hand, the data center, PC, broadband. In theera of the "Internet of Things", reinforced concrete, cable with the chip, broadband integration into a unified infrastructure, in this sense, the infrastructure is more like a new site of the Earth, the world really works it, which including economic management, production operation, social and even personal life. "Internet of Things" makes it much more refined and dynamic management of production and life, to manage the future of the city to achieve the status of "wisdom" to improve resource utilization and productivity levels, and improve the relationship between man and nature. 8.Agency1, institution-buildingAs the first national Internet of Things industry community organizations - the application of professional Committee of China Electronic Chamber of Things technology products (referred to as: "objects of the IPCC"), the Ministry of Civil Affairs in June 2010, preliminary approved by the Ministry of August being reported that the Ministry of Civil Affairs for final approval.2, the main taskServe as a bridge between business and government to assist the Government of the industry guidance, coordination, consultation and services to help members to reflect the business requirements to the Government; coordinate the relationship between enterprises to strengthen technical cooperation, product distribution, the elimination of vicious competition ; supervision of members the correct implementation of national laws and regulations, to regulate the industry; member of information communication technology products, cooperation, resource sharing, capital operation, and promote the application of Internet of Things technologies and products, and promote the Internet of Things industrial scale , co-development.9.ConstructionInternet of Things in the practical application to carry out requires the involvement of all walks of life, and need the guidance of the national government as well as related regulations and policies to assist the launching of the Internet of Things has the scale, broad participation, management, technical, and material properties, etc. other features, the technical problem is the most crucial issues of Things billion Bo logistics consulting, Internet of Things technology is an integrated technology, a system not yet which company has overall responsibility for network planning and construction of the entire system, theoretical studies have commenced in all walks of life and the practical application is limited to within the industry. The key is on the planning and design andresearch and development of the Internet of Things research in the field of RFID, sensors, embedded software, and transmission of data calculation. In general, to carry out the steps of the Internet of things mainly as follows:(1) identified the object attributes, properties, including static and dynamic properties of the static property can be stored directly in the label, the dynamic properties need to start with sensors to detect real-time;(2) the need to identify the equipment to complete the reading of object attributes, and information into a data format suitable for network transmission;(3) the object of information transmitted over the network to the information processing center (processing center may be distributed, such as home computers or mobile phones, may also be centralized, such as China Mobile IDC) by the processing center to complete the object communication calculation.10.key areasInternet of Things 4 key areas:(1) RFID;(2) sensor network;(3) The M2M;(4) integration of the two.11.TrendIndustry experts believe that the Internet of things on the one hand can improve economic efficiency and significant cost savings; the other hand, can provide technical impetus to global economic recovery. Currently, the United States, the European Union are all invested heavily in-depth study to explore the Internet of Things. The country is also highly concerned about the emphasis of Things, Industry and Information Technology Ministry in conjunction with the relevant departments are conducting research in a new generation of IT to the formation of policies and measures to support the development of a new generation of IT.China Mobile CEO Wang Jianzhou has repeatedly mentioned the Internet of Things will become the focus of future development of China Mobile. He will be invited to Taiwan to produce RFID, sensors and bar code manufacturers and China Mobile. According to him, the use of the Internet of Things technology, Shanghai Mobile has a number of industrial customers tailor the datacollection, transmission, processing and business management in one set of wireless application solutions. The latest data show that Shanghai Mobile has more than 100,000 chips mounted on a taxi, bus, various forms of matter networking applications in all walks of prowess, to ensure the orderly operation of the city. During the Shanghai World Expo, "the bus services through" will be fully applied to the Shanghai public transport system, the smooth flow traffic to the most advanced technology to protect Expo area; for logistics transportation management, e-logistics ", will provide users with real-time accurate information of Cargo, vehicle tracking and positioning, the transport path selection, logistics network design and optimization services greatly enhance the comprehensive competitiveness of logistics enterprises.In addition, the popularization of the "Internet of Things" for the number of animals, plants and machinery, sensors and RFID tags of items and related interface devices will greatly exceed the number of mobile phones. The promotion of the Internet of Things will become a drive to promote economic development for the industry to open up a potential development opportunities. According to the current demand on the Internet of Things, in recent years, billions of sensors and electronic tags, which will greatly promote the production of IT components, while increasing the number of job opportunities.According to reports, it is necessary to truly build an effective Internet of things, there are two important factors. First, the scale, only with the scale to make the items of intelligence play a role. For example, a city of one million vehicles, if we only 10000 vehicles installed on the smart system, it is impossible to form an intelligent transportation system; two mobility items are usually not static, but in the state of the movement , we must maintain the items in the state of motion, and even high-speed motion state can at any time for dialogue.FORRESTER of the authority of the U.S. advisory body predicted that 2020, the world of business of the Internet of Things, compared with the business of interpersonal communication, will reach 30 to 1, so the "Internet of Things" is known to be the next one trillion communications services.Internet of Things heat wave Why is rapidly growing in China? Internet of Things in China rapid rise thanks to the several advantages of our country in terms of things.In the early 1999 launched the Internet of Things core sensor network technology research, R & D level in the world; the second, sensor network field in the world, China is the standard one ofthe dominant country, the patent owner; third China is one of the countries to achieve a complete industrial chain of Things; Fourth, China's wireless communications network and broadband coverage provides a solid infrastructure to support the development of the Internet of Things; Fifth, China has become the world's first the three major economies, with strong economic strength to support the development of the Internet of Things.12.MythThe current understanding of the Internet of things there are a lot of misunderstanding, which is also a direct impact on our understanding of Things on the development of the logistics industry, it is necessary first to distinguish errors, clarify our thinking.One sensor networks or RFID network equivalent of Things. The fact that sensor technology, or RFID technology, or are simply one of the information collection technology. In addition to the sensor technology and RFID technology, GPS, video recognition, infrared, laser, scanning can be achieved automatically identify physical objects to communicate technical information collection technology can become the Internet of Things. Sensor networks or RFID network is just an application of Things, but not all of Things.Second, the Internet of Things as a myriad of unlimited extension of the Internet of Things as a completely open for all things, all of the interconnections, all shared Internet platform.In fact, the Internet of Things is not simple infinite extension of the global sharing of the Internet. Even if the Internet is also not only refers to we typically think of the international sharing computer network, Internet, WAN and LAN. Internet of Things can be both an extension of our usual sense of the Internet to the matter; LAN, professional can also be based on real needs and industrial applications. The reality is not necessary and can not make all the items networking; no need to make professional, LAN must be connected to the global Internet sharing platform. Of things in the future the Internet will be very different from the professional network of similar smart logistics, smart transportation, smart grid; the intelligence community and other local area network is the largest use of space.Ter, that the ubiquitous network of the Internet of Things Internet of Things, and therefore the Internet of Things is a castle in the air, is difficult to achieve the technology. In fact the Internet of things are real, many of the primary Internet of Things applications already for our services. The Internet of Things concept is introduced in many real-world applications based on polymericintegrated innovation, pre-existing network with the Internet of Things, intelligent, automated system, summarized and upgrading it upgraded from a higher perspective our knowledge.Four of Things as a basket, and everything installed inside; based on self-awareness, and only be able to interact, communication products as the Internet of Things applications. For example, just embedded some of the sensors, to become the so-called Internet of Things appliances; products labeled with RFID tags, became the Internet of Things applications.esThings widely used throughout the intelligent transportation, environmental protection, government, public safety, peace at home, smart fire, industrial monitoring, environmental monitoring, elderly care, personal health, floriculture, water monitoring, food traceability, enemy detection and intelligence collection and other fields.International Telecommunication Union in 2005, a report has portrayed the picture of the era of the "Internet of Things": car when the driver operational errors will automatically alarm; briefcase will remind the owner forgot something; clothes will "tell" washing machine color and water temperature requirements. Billion Bo logistics consulting vivid introduction of Things in the logistics field, for example, a logistics company, application of Things truck, when loading overweight, the car will automatically tell you overloaded and overload how many, but the space remaining , the severity of goods with how to tell you; when handling staff unloading a cargo packaging may be shouting "throw you hurt me", or "My dear, you do not get too barbaric, you can?"; when the driver and others gossip, trucks will pretend boss's voice roaring "stupid, the grid!Internet of things to make full use of a new generation of IT technology in all walks of life among, specifically, is embedded sensors and equipment to the power grid, railways, bridges, tunnels, highways, buildings, water systems, dams, oil and gas pipelines, etc.kinds of objects, and then "Internet of Things" with the existing Internet to integrate and realize the integration of human society and the physical system, which in this integrated network, there is the ability to super-powerful central computer cluster, integrated network staff implementation of real-time management and control of the machinery, equipment and infrastructure, on this basis, the human can be more refined and dynamic management of production and life, to achieve the status of the "wisdom", to improve resource utilization and productivity levels, and improve human the relationship between the natural.。

物联网英译汉1. Internet of Things (IoT) is an integrated part of Future Internet and could be defined as a dynamic global network infrastructure with self configuring capabilities based on standard and interoperable communication protocols where physical and vi rtual “things” have identities, physical attributes, and virtual personalities and use intelligent interfaces, and are seamlessly integrated into the information network.2. Unquestionably, the main strength of the IoT idea is the high impact it will have on several aspects of everyday-life and behavior of potential users. From the point of view of a private user, the most obvious effects of the IoT introduction will be visible in both working and domestic fields. In this context, domotics, assisted living, e-health, enhanced learning are only a few examples of possible application scenarios in which the new paradigm will play a leading role in the near future. Similarly, from the perspective of business users, the most apparent consequences will be equally visible in fields such as, automation and industrial manufacturing, logistics, business/process management, intelligent transportation of people and goods.3. In the IoT, “things” are expected to become active participants in business, information and social processes where they are enabled to interact and communicate among themselves and with the environment by exchanging data and information “sensed” about the environment,while reacting autonomously to the “real/physical world” events and influencing it by running processes that trigger actions and create services with or without direct human intervention.Lesson 1 History of Internet in a NetshellHere’s a brief history of the Internet, including important dates, people, projects, sites, and other information that should give you at least a partial picture of what this thing we call the Internet really is, and where it came from.While the complete history of the Internet could easily fill a few books, we should familiarize you with key milestones and events related to the growth and evolution of the Internet between 1969 to 2009.1969: ArpanetArpanet was the first real network to run on packet switching technology (new at the time).

第一题:The proposed IoT architecture from a technical perspective is shown in Fig. 1. It is divided into three layers. The basic layer and their functionalities are summarized as follows: Perception layer: its main function is to identify objects and gather information. It is formed mainly by sensors and actuators, monitoring stations (such as cellphone, tablet PC, smart phone, PDA, etc.), nano-nodes, RFID tags and readers/ work layer: it consists of a converged network made up of wired/wireless privately owned networks, Internet, network administration systems, etc. Its main function is to transmit information obtained from the perception layer.Application layer: it is a set of intelligent solutions that apply the IoT technology to satisfy the needs of the users.2.1. Perception layerThis layer provides context-aware information concerning the environment of disabled people. The components of this layer according to the disability of the person (visually impaired, hearing impaired or physically impaired) are described next.The components designed for the visually impaired are:(1) body micro-and nano-sensors and (2) RFID-based assistive devices. Next, those components are introduced.(2001), a retinal prosthesis is developed to restore some vision to patients affected by retinitis pigmentosa and age-related macular degeneration, two diseases that cause degenerative blindness. Although these disorders are characterized by the progressive loss of photoreceptor (rod and cone)cells of the outer retina, they do not affect the inner retinal ganglion nerve cells which form the optic nerve(Ye etal.,2010). Consequently, a camera mounted on a pair of glasses can be used to transmit image data to an implant attached to the retina, which is formed by an array of body micro-sensors. This artificial retina (Schwiebert et al., 2001) uses electrical impulses to stimulate the appropriate ganglion cells, which convert these electrical impulses into neurological signals. The generated response is carried via the optical nerve to the brain.Currently, researchers are working to develop an artificial retina at the nanoscale. The venture Nano Retina is developing Bio-Retina, a bionic retina that incorporates severalnano-sized components in a tiny retinal implant (see Fig. 2). Bio-Retina is designed to replace the damaged photoreceptor in the eye with the equivalent of a 5000 pixel (second generation)retinal implant. It transforms naturally received light into an electrical signal that stimulates the neurons, which send the images received by Bio-Retina to the brain. The implant’s nano-sized components are powered by a special pair of activation eyeglasses. In the next years, as technology evolves, it will be possible to send information concerning the images captured by the artificial retina towards the monitoring station (smart phone) (see Fig. 1), so that new IoT applications to help people with visual impairments in their orientation, identification of faces, etc. will be developed.(Saaid et al., 2009).The RFID cane (see Fig. 1) has a tag reader with an antenna that emits radio waves; the tags respond by sending back their stored data, hence identifying the location of the blind person. The tag reader (RFID cane) transmits via Bluetooth or ZigBee the data read fro m the RFID tag, which includes the tag ID string (D’Atri et al., 2007). This data is sent from the monitoring station through the network layer to the RFID server of the applicationlayer. The blind person can record the destination’s name as a voice message using the monitoring station. Directions are received by the monitoring station and played as voice messages (Shiizu et al., 2007).An obstacle detection system based on an ultrasonic sensor can also be added (Martin et al., 2009). The sensor is mounted on the RFID cane to extend its effective range and perceive obstacles the cane alone would not be able to detect (such as a garbage can in Fig. 1). A voice message played at the monitoring station alerts the visually impaired when an obstacle is detected. A multiple sensor-based shoe-mounted sensor interface is also developed in Zhang et al.(2010) as a supplementary device to the cane to detect obstacles within 61 cm ahead of the visually impaired.A widespread approach for outdoor navigation relies on Global Positioning System (GPS). It does not require tags to work. However, its resolution is limited (few meters) and it cannot work properly indoors. Therefore, some navigation systems for the visually impaired integrate both technologies (RFID and GPS) ( Yelamarthi et al., 2010).This layer (see Fig. 1) enables the access of the monitoringstations to the radio channel to transmit the information obtained from the perception layer. Although the Internet protocols were originally designed for fixed networks, there is a growing need for these protocols to accommodate mobile networks, as demonstrated by the use of many different wireless access technologies in IoT (EU FP7 Project CASAGRAS,The convergence of heterogeneous networks and applications is possible due to the existence of a single Internet Protocol (IP)- based network. The IP for Smart Object (IPSO) Alliance is a non- profit association of more than 50 members from leading technology, communications and energy companies. They advocate the use of IP networked devices to build the IoT (Dunkels and Vasseur, 2010). They stress that IP is a long-lived and stable communication technology that supports a wide range of applications, devices and underlying communication technologies. In addition, the end-to-end IP architecture is lightweight, highly scalable and efficient. Furthermore, the authors of Internet ? also recommend the use of the IP protocol to offer the Internet’s interoperability and scalability directly to embedded devices rather than needing gateways for protocol conversion(Gershenfeld and Cohen, 2006).It is necessary to ensure the connectivity, interoperability and compatibility of heterogeneous networks. The low-power net- working industry, from ZigBee ad hoc control to industrial automation standards (e.g. ISA100), is quickly converging to the use of IP technology (Shelby and Bormann, 2009). In this sense, 6LoWPAN is the name of a working group of the Internet Engineering Task Force (IETF) that has developed a set of Internet standards, which enable the efficient use of IPv6 over Low-power Wireless Personal Area Networks (6LoWPANs). 6LoWPAN enables resource-limited embedded devices (often battery-powered) in low-power wireless networks to be Internet-connected by simplifying IPv6 (header compression of IPv6 header fields) and taking the nature of wireless networks into account.The IPv6 protocol stack with 6LoWPAN is shown in Fig. 4. A small adaptation layer (named the LoWPAN adaptation layer) has been defined in the 6LoWPAN protocol stack (see Fig. 4) to optimize the transmission of IPv6 packets over IEEE 802.15.4 and similar link layers (Shelby and Bormann, 2009). IEEE 802.15.4 is a standard that defines the physical and MAC layers for low-power, low-rate wireless embedded radio communications at 2.4 GHz, 915 MHz and 868 MHz .The adoption of Internet protocols by wireless embedded devices is challenging due to several reasons (Shelby and Bormann, 2009):Battery-powered wireless devices require low duty cycles, whereas IP is based on always connected devices.Multicast is not supported natively in IEEE 802.15.4 but it is essential in many IPv6 operations.Sometimes it is difficult to route traffic in multi-hop wireless mesh networks to achieve the required coverage and cost efficiency.Low power wireless networks have low bandwidth (20–250 kbit/s) and frame size (IEEE 802.15.4 packets are rather small, 127 bytes maximum at the physical layer, minus MAC/security and adaptation layer overhead). On the other hand, the minimum datagram size that all hosts must be prepared to accept, for IPv6 is 1280 bytes. IPv6 requires that every link in the Internet has a Maximum Transmission Unit (MTU) of 1280 bytes or greater. On any link that cannot convey a 1280-byte packet in one piece, link-specific fragmentation and reassembly must be provided at a layer below IPv6.Standard protocols do not perform well in low-power wireless networks. For example, TCP performs very poorly in wireless networks due to its inability to distinguish between packet losses due to congestion and those due to channel error.2.3. Application layerThis layer (see Fig. 1) provides an operation support plat form, which can be accessed by monitoring stations and applications. It provides important functionalities such as authentication, billing, service management, service acceptance and routing of packets based on defined policies. IP Multimedia Subsystem (IMS) is a transport platform well-suited to perform these functions (Domingo, 2011), since services can be offered to the subscribers independently of the access media used, heterogeneous networks can be easily integrated and new applications and services can be rolled out faster reusing well defined common functions such as authentication, service provision, billing, group management and presence. This way, the IoT can be uniformly managed.The Web of Things (WoT) is a vision where smart objects are integrated with the Web. Smart object applications can be built on top of Representational State Transfer (REST) architectures(Fielding and Taylor). The REST architectural style decouples applications from the services they provide, which can be shared and reused. The key abstractions of information in the REST architecture are resources (e.g. a document or image). Resources in web-based REST systems are identified by Universal Resource Identifiers (URIs). REST-style architectures consist of clients and servers. Clients initiate requests to servers; servers process these requests and return the appropriate responses. Resources are accessed by clients using methods such as GET, PUT, POST and DELETE of Hypertext Transfer Protocol (HTTP). The resources themselves are conceptually separate from the representations that are returned to the client. For example, the server does not send its database, but rather, perhaps, some HyperText Markup Language (HTML), Extensible Markup Language (XML) or Java- Script Object Notation (JSON) that represents some database records depending on the details of the request and the server implementation.A web service is a software system designed to support inter- operable machine-to-machine interaction over a network. Web services enable the communication between processes applying REST for the manipulation of resources using HTTP, or Simple Object Access Protocol (SOAP) for sending messages and makingRemote Procedure Calls (RPCs) in a distributed environment. The Internet Engineering Task Force (IETF) Constrained REST- ful environments (CoRE) working group has defined a REST based web transfer protocol called Constrained Application Protocol(CoAP) (Shelby et al., 2011). The aim of CoAP is to extend the REST architecture for constrained IoT devices and networks (e.g. 6LoWPAN). It has been designed taking into account the requirements of important Machine-to-Machine (M2M) applica-tions such as energy and building automation. We also think it is appropriate for the IoT applications for people with disabilities. CoAP consists of a subset of REST common with HTTP functionalities, which have been optimized for M2M applications. CoAP offers features for M2M applications such as very low overhead, multicast support and asynchronous message exchanges. 第二题3. Application scenariosNext, several application scenarios of the Internet of Things for handicapped people are introduced. They illustrate the interaction of the different components of the IoT architecture.3.1. Shopping scenarioIn this scenario, people with visual impairments shop autonomously as shown in Fig. 6. The blind navigation system helps them to find th eir way in a store. The store’s RFID system can use software to guide the visually impaired in shopping. In Lo′ pez-de- Ipin?a et al.(2011), an RFID-tag based navigation system is proposed. The supermarket is divided into cells containing a shelf and passageway cells. RFID tags are distributed through the floor. The tag IDs within a cell are mapped to navigation information such as the type of a given cell and the types of neighboring cells. The monitoring station (smart phone) maintains a Bluetooth connection with the RFID reader (smart cane) of the user to keep track of his/her position anytime using the mapping of tag IDs with navigation information. The speech synthesis and recognition module of the monitoring station (smart phone) enables the visually impaired person to say the section of the supermarket where he/she wants to go. The route to follow is obtained invoking web services through a WLAN connected to the Internet. As the visually impaired walks, routing directions from an android application are received through the headphone of the smart phone and played as voice messages.RFID tags attached to the supermarket products supply pro- ductdata such as name, description and price. Sensor enabled RFID tags provide essential data such as temperature or shocks during transportation. The tag reader (RFID cane) transmits the tag ID string to the monitoring station, which forwards it to the RFID server (Krishna et al., 2008). Product information is returned from the RFID database to the monitoring station and played as voice messages. Additional product characteristics can include food composition, caloric intake and specific data related to the user profile such as food allergies and intolerances. Friend’s opinions about the product and price comparison w ith similar ones can be obtained using social networks. In Krishna et al. (2008), experiments of the RFID system were conducted to study detection range of RFID readers with respect to different tags and materials (where the tag is installed); it was concluded that the product materials did not affect the performance of the RFID readers.Several practical works have been developed related to this application scenario (Kulyukin and Kutiyanawala, 2010; Lanigan et al., 2007; Narasimhan , 2006; Nicholson et al., 2009; Winlock et al., 2010). In Lanigan et al. (2007) the authors propose Trinetra, a system designed to assist blind people in grocery shopping for product search and identification. As thevisually impaired scans a grocery item with a portable barcode or RFID reader, the scanned input is sent via Bluetooth to the user’s smart phone, which checks its cache for a product match. In case of cache miss, the smart phone communicates through GPRS with a remote server or, in case of miss, with a public Universal Product Code (UPC) or RFID database, which converts the barcode or tag into a human- interpretable product name (and related information) and returns it to the smart phone. An onboard text-to-speech software in the smart phone converts the displayed text into speech. The advan- tages of RFID tags compared to barcodes are reprogrammability , ability to contain more product information and ability to read without line-of-sight reading (Narasimhan, 2006). Trinetra was successfully tested at the Carnegie M ellon University’s campus store.ShopTalk (Nicholson et al., 2009) is a wearable system to assist visually impaired shoppers. The users get verbal instructions from a handheld computer. Modified Plessey (MSI) barcodes located on the shelves enable navigation within the store. UPC barcodes enable product localization in a store aisle. In a production version, the system would connect to the store’s inventory control database and look up product information.Successful experiments with visually impaired participants were performed at supermarkets.GroZi (Winlock et al., 2010) focuses on real-time product detection from mobile video in grocery stores. A user compiles a shopping list of products on the website and uploads it on a portable device. Later, the shopper scans a scene in the super- market with a camera. GroZi uses in vitro images of items (images of products taken under ideal lighting and perspective conditions) on the user’s shopping list to detect items in situ (from actual video stream). A hand glove with vibrating motors and the audio of the portable device are used to guide the shopper. The capability of detecting a shopping list’s items is demonstrated with experiments.Automatic payment can also be performed using RFID. A scanner reads all items in the cart at once, totals them up and charges the customer’s account while adjusting the inventory. RFID credit cards use a radio frequency to transmit personal financial data.Furthermore, periodic reports and statistics concerning the shopping can be computed and sent periodically from the monitoring server to the monitoring station.第三题5. Research challengesNext, the research challenges to IoT for people with disabilities are introduced.A key challenge is customization for people with disabilities. Since handicapped people have special needs, the IoT should be adapted to their particular circumstances. Smart workflows are context-aware processes that are executed pervasively. They take context-aware decisions based on context information of the environment captured automatically by sensors. The authors in Wieland et al.(2008) describe an architecture that converts lowlevel context-aware information captured by sensors into information at the business level using smart workflows. Developers use business process modeling tools to describe smart workflow tasks. Presto is a model-based (Giner et al.,2010) software architecture that captures the concepts that are involved in the interaction between physical elements and their digital counter- parts. When the business models are deployed in an execution engine, humans are usually required to perform some tasks in a workflow. Presto’s architecture processes these demands and offers the appropriate mechanisms for users tocomplete these tasks by enabling their interaction with the physical world. The resulting system is capable of presenting to each participant in the process the services associated with his/her context (physical environment) according to his/her role and current pending tasks. This way, the user is guided through a workflow. For example, if a library member with a monitoring station (PDA) enters the library, Presto shows in the monitoring station the tasks that the user can initiate and complete depending on the available task processors. We propose that if the user is disabled, the list of tasks is received in an appropriate way. For instance, the return boxes of the library automatically detect the returned books by means of RFID. If the disabled person selects the ‘return book’ option, different ways to orient the user towards the closest return box according to his/her disability should be provided (visual or auditory related information, indications for paralytics about how to access the area where the return box is, etc.).Another significant challenge to the IoT for people with disabilities is self-management. It refers to the process by which the IoT manages its own operation without human intervention. For this purpose, support for self-configuration, self-healing,self-optimization and self-protectioncapabilities is required (Haller et al., 2009). Self-configuration is related to the automatic configuration of components; self-healing handles the automatic discovery and correction of faults; self-optimization focuses on the automatic monitoring and control of resources to ensure the optimal functioning with respect to the defined requirements; self-protection tackles the proactive identification and protection from arbitrary attacks. Self-healing is particularly important, since handicapped people usually depend on IoT devices to compensate for their disabilities. Therefore, the detection and elimination of faulty nodes and the design of efficient fault- tolerant algorithms are required. Standardization is also a very important challenge. It is necessary to create globally accepted standards to avoid interoperability problems. 6LoWPAN provides wireless internet connectivity to low-power devices with limited processing capabilities, so that they can be used in the IoT. As a result, with this standard, interoperability and integration with current heterogeneous Internet-aware devices is accomplished to expand the IoT for disabled people. On the other hand, existing mobility protocols like Mobile IP for IPv6 (MIPv6) or management protocols like Simple Network Management Protocol (SNMP) cannotbe directly applied to 6LoWPAN devices, since they are inefficient in terms of energy, communication and computation cost(Jara et al.,2010). Therefore, more research to adapt existing protocols or find new solutions is required. Furthermore, enabling people with disabilities to establish deeper contact with the outside world is challenging. IoT objects can automatically share pictures, comments and sensor data via social networks. For instance, relatives of a disabled person that belong to the same social network can obtain real-time data about the activities of the handicapped person (if he/she is sleeping, eating, leaving home, has fallen, etc.).This information is automatically sent by ‘smart objects’that surround the disabled person in his/her domestic environment (smart home) (Kranz et al., 2010). Although direct communication with devices via social networks seems to be an exciting and promising way of maintaining social contact, the possibility of machines flooding social networks with auto-generated content exists.The amount of traffic in the IoT will rise exponentially once connections between most objects are established in the next years. Scalability is required to guarantee the properfunctioning of the IoT with a very high number of nodes. Senseless communications between ‘things’ should be avoided to favor scalability, since they increase the communication overhead and energy consumption.However, a minimum number of connections between devices should be established for the proper functioning of applications (such as enough tag density and messages to orient a blind person).In addition, security and privacy issues are real (Zorzi et al.,2010). It is essential to guarantee the privacy of the IoT for people with disabilities, who are particularly vulnerable. The IoT should be protected against distributed denial-of-service attacks, which can be defined as the result of any action that prevents any part of the IoT from functioning correctly or in a timely manner. The vulnerabilities of applications and sensors are exploited to launch such attacks. Consequently, an efficient security framework should be developed.Cooperation between devices in the IoT is also indispensable (Zorzi et al., 2010). Scenarios where more capable nodes (monitoring stations) discover other resource-restricted nodes, synchronize with one another and help each other in reliable datadelivery seem very promising. Nowadays, most IoT mass consumer applications are mobile devices-centered, since monitoring stations are more likely to integrate sensing, computing and communication capabilities. However, we envision that over time more direct thing- to-thing connections (between ‘things’ that are currently considered resource-restricted) will be established as communication, proces- sing capabilities, technologies deployed for web services and energy harvesting techniques evolve.Finally, we envision that the IoT for disabled people (especially physically disabled individuals)will evolve dramatically in the following years. The advances of brain–computer interfaces(BCIs) made possible the development of prototypes such as brain- controlled prosthetic devices, wheelchairs, keyboards and com- puter games. In the following years BCI technologies will be brought out of the lab and transform into real-world applications (Milla′n et al.,2010). Disabled people will benefit from the advancements in BCI technology combined with assistive technologies in four basic application areas(Milla′n et al.,2010): communication and control (Internet browsing, e-mails), motor substitution (in particular grasping and assistive mobility), entertainment(gaming, music browsing, photo browsing and virtual reality) and motor recovery. Neurophysiological signals (electroencephalogram, EEG) originating from the brain will be used to control external devices phone, computer, bed), which means human beings will be fully embedded in the Internet of the Things.。
