【摘要】：车联网是智慧交通研究领域的重要内容之一，具有广阔的应用前景。车载自组网中路由算法的研究是当前最受关注的热点问题。由于车载网络中节点移动速度快、拓扑结构变化迅等特点，，车载网络路由算法的研究是一个难点。在参考已有路由协议的基础上，结合地理位置路由和层次路由的思想，提出一种基于锚节点的车载网地理路由算法，以降低车载网络的路由传输时延，提高包递送率和吞吐量，并在仿真平台下进行了仿真实验以证明其路由性能。在已有硬件平台的基础上对锂电池电动车的车载系统软件、硬件进行设计，并在实际应用中进行测试和分析。本课题依托国家级科技计划项目（项目编号：61272449、BY2013030-09），对锂电池电动车的车联网展开研究，主要研究内容如下： 1)介绍车载自组网络的结构特点，对已有的路由算法进行分类、分析与总结。着重研究了基于地理位置的路由协议，通过对其路由协议层的具体流程分析的基础上，结合分层路由思想，提出基于锚节点的车载网地理路由算法，核心思想是利用道路路灯做为锚节点，车辆通过锚节点对自身定位，结合道路网关及中心数据库，建立分层路由，通过这种方式可避免数据包的全网广播，缩短了路由查找过程，以达到降低路由开销、提高路由效率的目的。 2)在VanetMobiSim和NS2仿真平台上，选取接近现实场景的移动模型对提出的路由算法进行仿真，结果表明在传输时延，包递送率和吞吐量三个方面比典型的地理位置路由协议具有较好的性能。 3)在已有课题研究的基础上对锂电池电动车的车载终端进行硬件和软件的设计，分别从车辆节点和锚节点予以介绍，给出了体系结构图、部分电路及通信协议流程图。最后设计锂电池电动自行车的实验方案，并在捷奥比公司进行应用测试。
[Abstract]:Vehicle networking is one of the important contents in the field of intelligent transportation research, and has a broad application prospect. The research of routing algorithm in vehicular ad hoc network is the most concerned hot topic at present. Because of the fast movement speed of nodes and the rapid change of topology in vehicle network, the research of routing algorithm in vehicle network is a difficult point. On the basis of referring to the existing routing protocols and combining the idea of geographical location routing and hierarchical routing, a vehicle-borne network geographical routing algorithm based on anchor node is proposed to reduce the routing transmission delay of vehicle-borne network and improve the packet delivery rate and throughput. Simulation experiments are carried out on the simulation platform to prove its routing performance. On the basis of the existing hardware platform, the software and hardware of the on-board system of lithium battery electric vehicle are designed, and tested and analyzed in the practical application. Based on the national science and technology plan project (project number: 61272449, BY2013030 / 09), this paper studies the vehicle networking of lithium battery electric vehicle. The main research contents are as follows: 1) the structure characteristics of on-board ad hoc network are introduced. The existing routing algorithms are classified, analyzed and summarized. The routing protocol based on geographical location is studied emphatically. based on the analysis of the specific flow of its routing protocol layer and the idea of hierarchical routing, a vehicle-borne network geographical routing algorithm based on anchor node is proposed. The core idea is to use road street lamps as anchor nodes, vehicles to locate themselves through anchor nodes, combined with road gateways and central databases, to establish hierarchical routing, through which the whole network broadcast of data packets can be avoided. The routing lookup process is shortened in order to reduce the routing overhead and improve the routing efficiency. 2) on the VanetMobiSim and NS2 simulation platform, the proposed routing algorithm is simulated by selecting the mobile model close to the real scene. The results show that the transmission delay of the proposed routing algorithm is delayed. Packet delivery rate and throughput are better than typical geographical location routing protocols. 3) on the basis of the existing research, the hardware and software design of the vehicle terminal of lithium battery electric vehicle is carried out. The vehicle node and anchor node are introduced respectively, and the architecture diagram, some circuits and communication protocol flow chart are given. Finally, the experimental scheme of lithium battery electric bicycle is designed and tested in Geobi Company.
