A survey of inter-vehicle communication

signal range and drop out of the network, oth-er vehicles can join in, connecting vehicles to one another to create a mobile Internet. We de-termine that V ANET only covers a very small mobile network that is subject to mobility con-straints and the number of connected vehicles. Several characteristics of large cities, such as traffic jams, tall buildings, bad driver behav-iors, and complex road networks, further hin-der its use. Therefore, for V ANET, the objects involved are temporary, random and unstable, and the range of usage is local and discrete, i.e., VANET cannot provide whole (global) and sustainable services/applications for cus-tomers. Over the past several decades, there has not been any classic or popular implemen-tation of VANET. The desired commercial interests have not emerged either. Therefore, V ANET’s usage has begun to stagnate.In contrast to VANET, IoV has two main technology directions: vehicles’ neworking and vehicles’ intelligentialize. Vehicles’ net-working is consisting of V ANET (also called vehicles’ interconnection), Vehicle Telematics (also called connected vehicles) and Mobile Internet (vehicle is as a wheeled mobile termi-nal). Vehicles’ intelligence is that the integra-tion of driver and vehicle as a unity is more intelligent by using network technologies, which refers to the deep learning, cognitive computing, swarm computing, uncertainty artificial intelligence, etc. So, IoV focuses on the intelligent integration of humans, vehi-cles, things and environments and is a largerAbstract: The new era of the Internet of Things is driving the evolution of conventional Vehicle Ad-hoc Networks into the Internet of Vehicles (IoV). With the rapid development of computation and communication technologies, IoV promises huge commercial interest and research value, thereby attracting a large number of companies and researchers. This paper proposes an abstract network model of the IoV , discusses the technologies required to create the IoV , presents different applications b a s e d o n c e r t a i n c u r r e n t l y e x i s t i n g technologies, provides several open research challenges and describes essential future research in the area of IoV .Keywords: internet of vehicles; VANET; vehicle telematics; network modelI. I NTRODUCTIONAccording to recent predictions 1, 25 billion “things” will be connected to the Internet by 2020, of which vehicles will constitute a significant portion. With increasing numbers of vehicles being connected to the Internet of Things (IoT), the conventional Vehicle Ad-hoc Networks (VANETs) are changing into the Internet of Vehicle (IoV). We explore the reasons for this evolution below.As is well-known, V ANET [1] turns every participating vehicle into a wireless router or mobile node, enabling vehicles to connect to each other and, in turn, create a network with a wide range. Next, as vehicles fall out of theAn Overview of Internet of VehiclesYANG Fangchun, WANG Shangguang, LI Jinglin, LIU Zhihan, SUN QiboState Key Laboratory of Networking and Switching Technology Beijing University of Posts and Telecommunications, Beijing, ChinaV EHICULAR N ETWORKING1/7037738/The_Inter-net_of_Things_A_Study_in_Hype_Reality_Disrup-tion_and_Growtthe conventional Vehicle Ad-hoc Networks (V ANETs), Vehicle Telematics, and other con-nected vehicle networks have to evolve into the Internet of Vehicle (IoV). The question accordingly arises as to why such systems did not evolve into IoT, Internet or wireless mo-bile networks.The main reason is that some characteris-tics of IoV are different from IoT, Internet or wireless mobile networks. Firstly, in wireless mobile networks, most end-users’ trajectories follow a random walk model. However, in IoV , the trajectory of vehicles is subject to the road distributions in the city. Secondly, IoT focuses on things and provides data-aware-ness for connected things, while the Internet focuses on humans and provides information services for humans. However, IoV focuses on the integration of humans and vehicles, in which, vehicles are an extension of a human’s abilities, and humans are an extension of a vehicle’s intelligence. The network model, the service model, and the behavior model of human-vehicle systems are highly different from IoT, Internet or wireless mobile network. Finally, IoV interconnects humans within and around vehicles, intelligent systems on board vehicles, and various cyber-physical systems in urban environments, by integrating vehi-cles, sensors, and mobile devices into a global network, thus enabling various services to be delivered to vehicles and humans on board and around vehicles. Several researchers have referred to the vehicle as a manned computer with four wheels or a manned large phone in IoV. Thus, in contrast to other networks, ex-isting multi-user, multi-vehicle, multi-thing and multi-network systems need multi-level collaboration in IoV .In this paper, we first provide a network model of IoV using the swarm model and an individual model. We introduce existing re-search work focusing on activation and main-tenance of IoV. Then, we survey the various applications based on some currently existing technologies. Finally, we give several open re-search challenges for both the network model and the service model of human-vehicle sys-network that provides services for large cities or even a whole country. IoV is an open and integrated network system with high manage-ability, controllability, operationalization and credibility and is composed of multiple users, multiple vehicles, multiple things and multiple networks. Based on the cooperation between computation and communication, e.g., col-laborative awareness of humans and vehicles, or swarm intelligence computation and cog-nition, IoV can obtain, manage and compute the large scale complex and dynamic data of humans, vehicles, things, and environments to improve the computability, extensibility and sustainability of complex network systems and information services. An ideal goal for IoV is to finally realize in-depth integration of human-vehicle-thing-environment, reduce social cost, promote the efficiency of trans-portation, improve the service level of cities, and ensure that humans are satisfied with and enjoy their vehicles. With this definition, it is clear that V ANET is only a sub network of IoV. Moreover, IoV also contains Vehicle Telematics [2], which is a term used to define a connected vehicle interchanging electronic data and providing such information services as location-based information services, remote diagnostics, on-demand navigation, and au-dio-visual entertainment content. For IoV , Ve-hicle Telematics is simply a vehicle with more complex communication technologies, and the intelligent transportation system is an applica-tion of IoV , but vehicle electronic systems do not belong to IoV .In the last several years, the emergence of IoT, cloud computing, and Big Data has driven demand from a large number of users. Individ-ual developers and IT enterprises have pub-lished various services/applications. However, because V ANET and Vehicle Telematics lack the processing capacity for handling global (whole) information, they can only be used in short term applications or for small scale ser-vices, which limits the development and popu-lar demand for these applications on consumer vehicles. There is a desperate need for an openand integrated network system. Therefore,people who consume or provide services/ap-plications of IoV . Human do not only contain the people in vehicles such as drivers and pas-sengers but also the people in environment of IoV such as pedestrians, cyclists, and drivers’ family members. Vehicle in IoV terminology refers to all vehicles that consume or provide services/applications of IoV . Thing in IoV ter-minology refers to any element other than hu-man and vehicle. Things can be inside vehicles or outside, such as AP or road. Environment refers to the combination of human, vehicle and thing.The individual model focuses on one vehi-cle. Through the interactions between human and environment, vehicle and environment, and thing and environment, IoV can provide services for the vehicles, the people and the things in the vehicles. In the model, the in-tra-vehicle network is used to support the interaction between human and vehicle, and the interaction between vehicle and thing in that vehicle. The inter-vehicle network is usedtems, i.e., enhanced communication through computation and sustainability of service pro-viding, and outline essential future research work in the area of IoV .The rest of this paper is organized as fol-lows. Section 2 describes o ur proposed net-work model of IoV. The overview of IoV is presented from three different perspectives in Section 3. In Section 4, several open research challenges and essential future research work related to IoV are outlined. Finally, we present this paper’s conclusions in Section 5.II. N ETWORK M ODEL OF IOVAs shown in Fig. 1, we propose a network model of IoV based on our previous work [3], in which the model is composed of a swarm model and an individual model. The key as-pect of the network model is the integration between human, vehicle, thing, and environ-ment.Human in IoV terminology refers to all theFig.1Network model of IoVsignificantly improve the quality of vehicle service, while a bad wireless access may often lead to the breakdown of services. As is well-known, routing technology is the research core of traditional networks. For IoV , while routing is still the core of the inter-vehicle network, it is also essential for delivering the control message. Finally, IoV has the two most im-portant elements, i.e., users and network. For a simple IoV, wireless access is its user, and routing is its network. With the development of IoV , however, these elements might be less important, and other technologies may play a vital role, such as collaboration technology and swarm intelligence computing. However, due to page limitations, a detailed discussion is beyond this paper.Note that the technologies introduced in this section cannot cover the technologies of IoV , and most of them belong to V ANET [4] or Ve-hicle Telematics. The reason is that IoV is an open and integrated network system composed of multiple users, multiple vehicles, multiple things and multiple networks, and an integrat-ed IoV is not described. Hence, this section mainly focuses on existing technologies and applications, even if they do not represent the technologies and applications of IoV .3.1 Activation of IoVThere are many steps in the activation of IoV , but the most important step is to take the vehi-cles into the integrated network of IoV using wireless access technologies. At present, there are many existing wireless access technologies such as WLANs, WiMAX, Cellular Wireless, and satellite communications [5]. As shown in Fig. 1, most of these technologies are used to connect vehicles to each other in IoV .WLAN contains IEEE 802.11a/b/g/n/p standards. IEEE 802.11-based WLAN, which has achieved great acceptance in the market, supports short-range, relatively high-speed data transmission. The maximum achievable data rate in the latest version (802.11n) is ap-proximately 100 Mbps. IEEE 802.11p is a new communication standard in the IEEE 802.11 family which is based on the IEEE 802.11a.to support the interaction between human and environment, vehicle and environment, and thing and environment. Swarm model focus-es on multi-user, multi-vehicle, multi-thing and multi-network scenarios. Through swarm intelligence, crowd sensing and crowd sourc-ing, and social computing, IoV can provide services/applications. Moreover, in this model, the interaction between human and human, ve-hicle and vehicle, and thing and thing, all need an integrated network to collaborate with each other and with the environment. Note that IoV has a computation platform for providing vari-ous decisions for whole network, and there are many virtual vehicles with drivers correspond-ing to physica vehicles and drivers. Then we call the virtual vehicle with driver as Autobot. In the IoV, Autobot can interact with each other by using swarm computing technologies and provide decision-making information for IoV in the computation platform.III. T ECHNOLOGY AND A PPLICATION OF IOVOver a decade ago, both industrial and aca-demic researchers proposed many advanced technologies for the application layer, the mo-bile model & the channel model, the physical layer & the data link layer, the network layer & the transport layer, and security & privacy; these technologies are all used in IoV . In this section, we only focus on giving an overview of the technologies and their applications in IoV, and do not describe the details of the technologies. The overview describes the acti-vation of the IoV , maintenance of the IoV , and IoV applications.For the activation and maintenance of the IoV, we only summarize the wireless access technology and the routing technology. There are several reasons for focusing on these two technologies. Firstly, most researchers working on IoV focus on wireless access and routing, for which the number of proposed re-search works are the highest. Secondly, wire-less access technologies play an important role in IoV . A good wireless access technology canquality of service, even for non-line-of-sight transmissions. The key advantage of WiMAX compared to WLAN is that the channel access method in WiMAX uses a scheduling algo-rithm in which the subscriber station needs to compete only once for initial entry into the network.Cellular wireless comprises of 3G, 4G and LTE. Current 3G networks deliver data at a rate of 384 kbps to moving vehicles, and can go up to 2 Mbps for fi xed nodes. 3G sys-tems deliver smoother handoffs compared to WLAN and WiMAX systems, and many nota-ble works have been proposed. For example, Chao et al. [8] modeled the 3G downloading and sharing problem in integration networks. Qingwen et al. [9] made the first attempt in exploring the problem of 3G-assisted data delivery in V ANETs. However, due to central-ized switching at the mobile switching center (MSC) or the serving GPRS support node (SGSN), 3G latency may become an issue for many applications. Vinel [3] provided an an-IEEE 802.11p is designed for wireless access in the vehicular environment to support intel-ligent transport system applications. The use of wireless LANs in V ANETs requires further research. For example, Wellens et al. [6] pre-sented the results of an extensive measure-ment campaign evaluating the performance of IEEE 802.11a, b, and g in car communication scenarios, and showed that the velocity has a negligible impact, up to the maximum tested speed of 180 km/h. Yuan et al. [7] evaluated the performance of the IEEE 802.11p MAC protocol applied to V2V safety communica-tions in a typical highway environment. Wi-MAX contains IEEE 802.16 a/e/m standards. IEEE 802.16 standard-based WiMAX are able to cover a large geographical area, up to 50 km, and can deliver significant bandwidth to end-users - up to 72 Mbps theoretically. While IEEE 802.16 standard only supports fixed broadband wireless communications, IEEE 802.16e/mobile WiMAX standard supports speeds up to 160 km/h and different classes of Fig.2 Wireless access technologies in IoVAPManagement and Control on the APIEEE 802.16WiMax DatabaseAP Management and Control on the APAPManagement and Control on the APCellular NetworkCellular NetworkDatabaseSatellite NetworkSatellite Network DatabaseAPManagement and Control on the APIEEE 802.11WLAN DatabaseVehicleVehicleVehicleVehicleCentralized Management and Control Unitand Control Unit (CMCU)NetworkDatabaseCMCUIoV3.2 Maintenance of IoVThere are also many aspects to the mainte-nance of IoVs, such as data-awareness, virtual networks, and encoding, but the most im-portant aspect is the switching of the control message for IoV. Routing technology is the suitable solution, and in IoV , is dependent on a number of factors such as velocity, density, and direction of motion of the vehicles. As shown in Fig. 1, vehicles can either be the source or the destination during the process of routing, and various standards have been built to accomplish the task of routing. With the growing needs of the users to access various resources during mobility, efficient techniques are required to support their needs and keep them satisfied.Topology based maintenance: Because of the large overhead incurred for route discovery and route maintenance for highly mobile unco-ordinated vehicles, only a few of the existing routing protocols for inter-vehicle networks are able to handle the requirements of safety applications [10,11]. An important group of routing protocols for ad-hoc networks is based on topology, and needs the establishment of an end-to-end path between the source and the destination before sending any data packet. Due to rapid changes in the network topology and highly varying communication channel conditions, the end-to-end paths determined by regular ad-hoc topology-based routing pro-tocols are easily broken. To solve this prob-lem, several routing protocols have been pro-posed [12,13] [14,15] [16] [17]. For example, Namboodiri and Gao [12] proposed a predic-tion-based routing for V ANETs. The PBR is a reactive routing protocol, which is specifically tailored to the highway mobility scenario, to improve upon routing capabilities without us-ing the overhead of a proactive protocol. The PBR exploits the deterministic motion pat-tern and speeds, to predict roughly how long an existing route between a “node” vehicle and a “gateway” vehicle will last. Using this prediction, the authors pre-emptively create new routes before the existing route lifetimealytical framework which allows comparing 802.11p/WA VE and LTE protocols in terms of the probability of delivering the beacon before the expiration of the deadline. Lei et al. [4] studied the potential use cases and technical design considerations in the operator con-trolled device-to-device communications. The potential use cases were analyzed and classi-fied into four categories. Each use case had its own marketing challenges and the design of related techniques should take these fac-tors into consideration. Gerla and Kleinrock [5] discussed LTE cellular service in a future urban scenario with very high bandwidth and broad range. The so-called cognitive radios will allow the user to be “best connected” all the time. For instance, in a shopping mall or in an airport lounge, LTE will become congested, and the user’s cognitive radio will disconnect from LTE. For vehicles, due to large costs, sat-ellite communications are barely used, except for GPS. It is only a supplement for temporary and emergency uses, when other communica-tion technologies are invalid or unavailable. Looking at the wireless access technologies described above, we think that the 4G or LTE should be the most efficient technology to launch the inter-vehicle network and to acti-vate the IoV . The reasons are as follows. First-ly, 4G or LTE is the most used communication standard, and has been deployed by most countries to provide access services. Obvious-ly, any vehicle can use it to connect to the IoV . Secondly, in the context of high buildings and a complex city environment, the performance of 4G or LTE is the best among all wireless access technologies. Finally, in the past ten years, the development of VANET has been very slow, and can barely be used in the real world. The main reason is that the connected vehicles cannot maintain V ANET in city roads because the goals of drivers are random and different. To maintain the V ANET, all vehicles must access the integrated network of IoV, after which IoV can be activated to provide services for users.which combines store-carry-and-forward tech-nique with routing decisions based on geo-graphic location. These geographic locations are provided by GPS devices. In GeoSpray, authors proposed a hybrid approach, mak-ing use of a multiple copy and a single copy routing scheme. To exploit alternate paths, GeoSpray starts with multiple copy schemes which spread a limited number of bundle cop-ies. Afterwards, it switches to a single copy scheme, which takes advantage of additional opportunities. It improves delivery success and reduces delivery delay. The protocol ap-plies active receipts to clear the delivered bun-dles across the network nodes. Compared with other geographic location-based schemes, and single copy and non-location based multiple copy routing protocols, it was found that Geo-Spray improves delivery probability and re-duces delivery delay. In contrast to the above work, Bernsen and Manivannan proposed [20] a routing protocol for V ANETs that utilizes an undirected graph representing the surrounding street layout, where the vertices of the graph are points at which streets curve or intersect, and the graph edges represent the street seg-ments between those vertices. Unlike existing protocols, it performs real-time, active traffic monitoring and uses these data and other data gathered through passive mechanisms to as-sign a reliability rating to each street edge. Then, considering the different environments, a qualitative survey of position-based rout-ing protocols was made in [21], in which the major goal was to check if there was a good candidate for both environments or not. An-other perspective was offered by Liu et al. [22], who proposed a relative position based message dissemination protocol to guarantee high delivery ratio with acceptable latency and limited overhead. Campolo et al. [23] used the time, space and channel diversity to improve the efficiency and robustness of network ad-vertisement procedures in urban scenarios. Clustering based maintenance: In this type of routing scheme, one of the nodes among the vehicles in the cluster area becomes a clusterhead (CH), and manages the rest ofexpires. Toutouh et al. [13] proposed a well-known mobile ad hoc network routing proto-col for V ANETs to optimize parameter settings for link state routing by using an automatic optimization tool. Nzounta et al.[15] proposed a class of road-based VANET routing proto-cols. These protocols leverage real-time ve-hicular traffic information to create paths. Fur -thermore, geographical forwarding allows the use of any node on a road segment to transfer packets between two consecutive intersections on the path, reducing the path’s sensitivity to individual node movements. Huang et al. [16] examined the efficiency of node-disjoint path routing subject to different degrees of path coupling, with and without packet redundancy. An Adaptive approach for Information Dis-semination (AID) in VANETs was presented in [14], in which each node gathered the in-formation on neighbor nodes such as distance measurements, fixed upper/lower bounds and the number of neighboring nodes. Using this information, each node dynamically adjusts the values of local parameters. The authors of this approach also proposed a rebroadcast-ing algorithm to obtain the threshold value. The results obtained show that AID is better than other conventional schemes in its cate-gory. Fathy et al. [17] proposed a QoS Aware protocol for improving QoS in VANET. The protocol uses Multi-Protocol Label Switching (MPLS), which runs over any Layer 2 technol-ogies; and routers forward packets by looking at the label of the packet without searching the routing table for the next hop.Geographic based maintaining. The geo-graphic routing based protocols rely mainly on the position information of the destination, which is known either through the GPS sys-tem or through periodic beacon messages. By knowing their own position and the destination position, the messages can be routed directly, without knowing the topology of the network or prior route discovery. V . Naumov et al. [18] specifically designed a position-based routing protocol for inter-vehicle communication in a city and/or highway environment. Soares et al. [19] proposed the GeoSpray routing protocol,dynamic transmission range, the direction of vehicles, the entropy, and the distrust value parameters. Wang et al. [26] refined the orig -inal PC mechanism and proposed a passive clustering aided mechanism, the main goal of which is to construct a reliable and stable clus-ter structure for enhancing the routing perfor-mance in V ANETs. The proposed mechanism includes route discovery, route establishment, and data transmission phases. The main idea is to select suitable nodes to become cluster-heads or gateways, which then forward route request packets during the route discovery phase. Each clusterhead or gateway candidate self-evaluates its qualification for clusterhead or gateway based on a priority derived from athe nodes, which are called cluster members. If a node falls in the communication range of two or more clusters, it is called a border node. Different protocols have been proposed for this scheme, and they differ in terms of how the CH is selected and the way the routing is done. R. S. Schwartz et al. [24] proposed a dissemination protocol suitable for both sparse and dense vehicular networks. Suppression techniques were employed in dense networks, while the store-carry-forward communication model was used in sparse networks. A. Daein-abi [25] proposed a novel clustering algorithm - vehicular clustering - based on a weighted clustering algorithm that takes into consider-ation the number of neighbors based on theavoidance. At present, collision avoidance technologies are largely vehicle-based systems offered by original equipment manufacturers as autonomous packages which broadly serve two functions, collision warning and driver assistance. The former warns the driver when a collision seems imminent, while the latter partially controls the vehicle either for steady-state or as an emergency intervention [41]. To be specific, collision warning includes notifi -cations about a chain car accident, warnings about road conditions such as slippery road, and approaching emergency vehicle warning [5]. On the one hand, collision warnings could be used to warn cars of an accident that oc-curred further along the road, thus presenting a pile-up from occurring. On the other hand, they could also be used to provide drivers with early warnings and prevent an accident from happening in the first place. Note that driving near and through intersections is one of the most complex challenges that drivers face be-cause two or more traffic flows intersect, and the possibility of collision is high [42]. The intelligent intersection, where such conven-tional traffic control devices as stop signs and traffic signals are removed, has been a hot area of research for recent years. Vehicles coordi-nate their movement across the intersection through a combination of centralized and dis-tributed real-time decision making, utilizing global positioning, wireless communications and in-vehicle sensing and computation 1. A number of solutions for collision avoidance of multiple vehicles at an intersection have been proposed. A computationally efficient control law [43-45] has been derived from ex-ploitation of the monotonicity of the vehicles’ dynamics, but it has not been applied to more than two vehicles. An algorithm that addresses multi-vehicle collisions, based on abstraction, has been proposed in [46]. An algorithmic ap-proach to enforcing safety based on a time slot assignment, which can handle a larger number of vehicles, is found in [41]. Colombo et al. [47] designed a supervisor for collision avoid-ance, which is based on a hybrid algorithm that employs a dynamic model of the vehiclesweighted combination of the proposed metrics. P. Miao [27] proposed a cooperative commu-nication aware link scheduling scheme, with the objective of maximizing the throughput for a session in C-V ANETs. They let the RSU schedule the multi-hop data transmissions among vehicles on highways by sending small sized control messages.Based on the above overview, we provide a relative comparison of all routing protocols in Tab 1. In this table, Route length is the total distance between source and destination. PDR is the packet delivery ratio. Latency is the in-terval of time between the first broadcast and the end of the last host’s broadcast. Latency includes buffering, queuing, transmission and propagation delays.3.3 IoV applicationsWith the rapid development of numeric infor-mation technology and network technology, it is brought forward that theautomatization and intelligentization of vehicle.This gives birth to lots of applications which combine safe driving with service provision. For example, Apple CarPlay, originally introduced as iOS in vehicles, offer full-on automobile integration for Apple’s Maps and turn-by-turn navigation, phone, iMeessage, and music service 5. Similar to CarPlay, Google Android Auto provides a distraction-free interface that allows drivers enjoy the services by connecting Android de-vices to the vehicle. Chinese Tecent recently launched its homegrown navigation app Lu-bao that features user generated contents and social functions 7. For demonstration purposes, in this paper, IoV applications can be divided into two major categories: Safety applications and User applications. Applications that in-crease vehicle safety and improve the safety of the passengers on the roads by notifying the vehicles about any dangerous situation in their neighborhood are called safety applications. Applications that provide value-added services are called User applications.Technologies to enhance vehicular and passenger safety are of great interest, and one of the important applications is collision。
