天线变形曲面的一种拟合方法
华慕麟
【期刊名称】《现代雷达》
【年(卷),期】1994(16)1
【摘要】各种雷达天线、卫星通信地面站天线的实际反射面都是变形曲面。

这种
变形曲面可以是具有一定制造误差的反射面，也可以是设计曲面在设计载荷作用下的变形反射面。

对变形曲面通过计算求其最佳拟合（又称吻合）曲面作为理想曲面，可以提高变形曲面的精度，从而达到降低成本、改善性能的效果。

本文介绍一种从最小二乘法原理出发求取最佳拟合曲面（包括平面）的方法，该方法实用、规范且思路清晰。

的晶格氧氧化为O 2,导致其结构不稳定㊂然而,纳米Ag 2O 在有机物污染物降解方面表现出良好的稳定性[55],这是因为Ag 2O 的表面会随着光化学反应的进行被一定数量的Ag 0纳米粒子所覆盖,而Ag 0纳米粒子作为光生e -陷阱,能够降低e -在Ag 2O 表面的富集,同时,由于光生h +具有较强的氧化性能力,既能实现对有机污染物的直接氧化,又能避免其对晶格氧的氧化,从而提高了纳米Ag 2O

4纳米片的表面,光催化性能测试结果表明在3h 的可见光照射下,其降解能力是β-Ag 2MoO 4和g-C 3N 4机械混合物的2.6倍,主要原因在于β-Ag 2MoO 4和g-C 3N 4两者界面间形成更为紧密的异质结,使得e -/h +对被快速分离㊂Wu 等[61]采用简单的原位沉淀方法成功构建了Ag 2MoO 4/g-C 3N 4光催化剂,并将其应用于MO㊁BPA 和阿昔洛韦的降解,结果表明该催化剂显示出良好的太阳光催化活性,这主要是因为Ag 2MoO 4和g-C 3N 4界面间存在着一定的协同效应,可有效地提高对太阳光的利用率,降低载流子的复合概率㊂2㊀g-C 3N 4/Ag 基二元复合光催化剂电荷转移机理模型研究g-C 3N 4/Ag 基二元复合光催化剂在可见光的辐照下,价带电子发生跃迁,产生e -/h +对㊂e -被催化剂表面吸附的O 2捕获产生㊃O

Simulation of the Global Routing Protocol based on NS-3Keng YeSchool of Information and Communication Engineering Beijing Information Science and Technology UniversityBeijing, Chinae-mail:**************Jinhe ZhouSchool of Information and Communication Engineering Beijing Information Science and Technology UniversityBeijing, Chinae-mail:*******************.cnAbstract—NS-3 (Network Simulator version 3) could construct a network environment to simulate protocols in computer network. The purpose of this paper is implementing global routing by using the NS-3 with modified OSPF source code. The processing of simulation had been described with C++ code. Furthermore, the result of the network simulation had been analyzed with different software tools such as gawk, gunplot. In this paper we focused on simulating the global routing of Internet by NS-3 and analyzing the related theories about the routing protocol, at last, this paper was analyzing the average delay under different rates.Keywords-routing protocol; NS-3; OSPF; simulationI.I NTRODUCTIONNS-3 not only had abandoned shortcomings of the current mainstream network simulation software such as OPNET and NS-2, but also integrated the advantages of them. NS-3 had excellence including the following aspects: (1) documenting kernel of the standard components; (2) using scripting language such as C + + or Python; (3) applying to real system (network interface, device, driver interface) perfectly; (4) software integration; (5) virtualization and test-bed integration; (6) excellent documented property system; (7) updating the model in real time.NS-3 is a kind of unique simulator which includes integrity, openness, scalability and etc, and these feathers make it superior to most of the existing mainstream network simulator software. NS-3 has extremely powerful function to simulate a variety of network, protocols at all levels.NS-3 is different from the NS-2, although NS-3 is still using the C++ language to realize the simulation node. It hadn’t supported on NS-2 API and obsoleted Otcl language to control the processing of simulation. The framework of NS-3, whose simulation process can be described by pure C++ code, is much clearer than other software [1].II.T HE P RINCIPLE OF G LOBAL R OUTING P ROTOCOLIn NS-3, a C++ object builds an OSPF (Open Shortest Path First) routing database of information about the network topology [2], and executes a Dijkstra SPF (Shortest Path First) algorithm on the topology for each node, and stores the computed routes in each node's layer 3 forwarding table by making use of the routing API(Application Program Interface). The format of the data exported harmonizes with the OSPFv2 standard. In particular, the information is exported in the form of ns3::GlobalLSA objects that semantically conform to the LSA (Link State Advertisements) of OSPF. By utilizing a standard data format for informing topology, existing OSPF route computation code can be reused, and that is what can be done by ns3::GlobalRouteManager objects.OSPF is one kind of IGP (Interior Gateway Protocol), which is used for making routing decision in a single AS (Autonomous System). OSPF is a kind of link-state routing protocol, while RIP is a kind of distance vector routing protocol. In the other words, link is called router interface, so OSPF is also known as the interface state routing protocol. The OSPF is establishing the link state database, generating the shortest path tree through the network interface state of router notice, each OSPF router using the shortest path to construct the routing table [3].The routing algorithm is the core of the OSPF routing protocol. The SPF algorithm is also called Dijkstra algorithm as shown in Fig. 1, because of the shortest path first algorithm SPF is invented by Dijkstra. The SPF algorithm utilize each router as root node to calculate the distance from root node to each destination router, according to a unified database each router will be worked out the topological structure in routing domain, which is similar to a tree called SPT( shortest path tree )in the SPF algorithm. In the OSPF routing protocol, the trunk length of SPT is the distance from the root router to other routers. Smaller Cost means that the OSPF distance between source and destination is shorter.S represents the set of nodes which have not found the shortest path to the root node.R [i]represents the node which is located in front the node i on the path from the specified source node to node i.D [i]represent the shortest distance from the specified source to the node i.Initialization of the algorithm:The set S is initialized as a set which include all nodes but the source node.D[i]: If there is a link from the source node to node v, D (v) is the Cost of the link; otherwise D (v) is infinity.R[i]: If there is a link from source node to node v, R (v) is source node; otherwise R (v) =0International Conference on Software Engineering and Computer Science (ICSECS2013)Figure 1. Pseudo code for Dijstra algorthmWhen the router is initializing or the network structure is changing (for example, increasing or decreasing in the router, link state changing), the router will generate LSA, which contains all of the routers connected to the link, and calculate the shortest path.All routers exchange data of link state with each other through a Flooding, which is that the routers sent LSA to all adjacent OSPF routers. Basing on which the routers received, they have been updating their database and forwarding link state information to the adjacent routers until a stable process When the network is re-stabilized, the convergences of OSPF routing protocol have been completed. All routers will be calculated by the respective link state database of information to generate routing table, which contains the router to another reachable one and the destination to the next router.III.T HE SIMULATION PROCESS OF GLOBAL ROUTINGIn this section, we’ll introduce some important terms that are realizing specific function in ns-3.A.NodeIn NS-3 the basic abstraction of network device is called the Node. The class Node provides methods for managing the functions of network devices in simulation. You should consider a Node as a computer or a router to which you will add functionality by yourself [1]. One adds things like topology, channel, protocol stacks and peripheral devices with their associated drivers to activate the Node to do practical function.Class NodeContainer provides a very convenient way to create, manage, and access nodes, set as follows,NodeContainer c;c.Create (7); B.TopologyClass NodeContainer can connect any two nodes, set asfollows,NodeContainer n0n4 = NodeContainer(c.Get(0), c.Get(4));C.ChannelThe class Channel provides methods for constructingcommunication subnetwork objects and connecting nodes toeach other. Channels may also be specialized by us in theobject- oriented programming method. The specializedChannel can simulate things as complicated as a wire, alarge Ethernet switch, or three-dimensional space full ofobstructions in the case of wireless networks [1].We will utilize specialized versions of the Channelcalled CsmaChannel, PointToPointChannel and WifiChannel in NS-3. This paper choosesPointToPointHelper to simulate, set as follows,PointToPointHelper p2p;DeviceIn ns-3 the abstraction of network device covers both thesoftware driver and the simulated hardware. A network device is “installed” in a Node so as to activate the Node tocommunicate with other Nodes in the simulation viaChannels. Just as in a real computer, a Node may beconnected to more than one Channel via multipleNetDevices. The abstraction of network device isrepresented in C++ by the class NetDevice. The classNetDevice provides methods for managing connections toNode and Channel objects; and may be specialized by us inthe object-oriented programming. We will utilize the severalspecialized versions of the NetDevice calledCsmaNetDevice, PointToPointNetDevice, andWifiNetDevice in NS-3[1]. This paper choosesPointToPointNetDevice to simulate, set as follows, p2p.SetDeviceAttribute ("DataRate", StringValue ("5Mbps"));NetDeviceContainer d0d4 = p2p.Install (n0n4);E.Protocol StackUntil now, nodes, devices and channels are created, wewill use class InternetStack to add stack, set as follows, InternetStackHelper internet;internet.Install (c);F.Assignning Ipv4 AddressThis paper chooses Class Ipv4AddressHelper assign IPaddresses to the device interfaces.NS_LOG_INFO ("Assign IP Addresses.");Ipv4AddressHelper ipv4;ipv4.SetBase ("10.1.1.0", "255.255.255.0");Ipv4InterfaceContainer i0i4=ipv4.Assign (d0d4); G.Setting OSPF Cost Metrici0i4.SetMetric (0, sampleMetric04);i0i4.SetMetric (1, sampleMetric04);H.Generating Routing TableNS_LOG_INFO is recording information on the progress of the program.

DelayIn Fig. 5 are shown the simulation results of delay for the communication between node 0 and node 3. Under different shortest path, delay is diverse. The network delay is very close to the case when the packets take the same path. The path of least delay is not necessarily the shortest path.The average delay is the time of all data packets arrived at destination node from the source node. The characterization means the current status of the network. As shown in Fig. 6,V.C ONCLUSIONSummary, this paper describes an effective simulation method to realize global routing protocols, evaluate network performance, and carry out a detailed analysis of delay and shortest path tree. The conclusion has certain reference value.A CKNOWLEDGMENTThis work was supported by National Natural Science Foundation of China (61271198) and Beijing Natural Science Foundation (4131003).Figure 5.the packet delayFigure 6. the average delay under different rateR EFERENCES[1] NS-3 Tutorial. /, 12 Dev 2012[2] NS-3 project NS-3 Doxygen. /,12 Dev 2012 [3] Andrew S.
