【摘要】：車聯(lián)網(wǎng)是智慧交通研究領(lǐng)域的重要內(nèi)容之一，具有廣闊的應(yīng)用前景。車載自組網(wǎng)中路由算法的研究是當(dāng)前最受關(guān)注的熱點(diǎn)問題。由于車載網(wǎng)絡(luò)中節(jié)點(diǎn)移動(dòng)速度快、拓?fù)浣Y(jié)構(gòu)變化迅等特點(diǎn)，，車載網(wǎng)絡(luò)路由算法的研究是一個(gè)難點(diǎn)。在參考已有路由協(xié)議的基礎(chǔ)上，結(jié)合地理位置路由和層次路由的思想，提出一種基于錨節(jié)點(diǎn)的車載網(wǎng)地理路由算法，以降低車載網(wǎng)絡(luò)的路由傳輸時(shí)延，提高包遞送率和吞吐量，并在仿真平臺(tái)下進(jìn)行了仿真實(shí)驗(yàn)以證明其路由性能。在已有硬件平臺(tái)的基礎(chǔ)上對(duì)鋰電池電動(dòng)車的車載系統(tǒng)軟件、硬件進(jìn)行設(shè)計(jì)，并在實(shí)際應(yīng)用中進(jìn)行測(cè)試和分析。 本課題依托國家級(jí)科技計(jì)劃項(xiàng)目（項(xiàng)目編號(hào)：61272449、BY2013030-09），對(duì)鋰電池電動(dòng)車的車聯(lián)網(wǎng)展開研究，主要研究?jī)?nèi)容如下： 1)介紹車載自組網(wǎng)絡(luò)的結(jié)構(gòu)特點(diǎn)，對(duì)已有的路由算法進(jìn)行分類、分析與總結(jié)。著重研究了基于地理位置的路由協(xié)議，通過對(duì)其路由協(xié)議層的具體流程分析的基礎(chǔ)上，結(jié)合分層路由思想，提出基于錨節(jié)點(diǎn)的車載網(wǎng)地理路由算法，核心思想是利用道路路燈做為錨節(jié)點(diǎn)，車輛通過錨節(jié)點(diǎn)對(duì)自身定位，結(jié)合道路網(wǎng)關(guān)及中心數(shù)據(jù)庫，建立分層路由，通過這種方式可避免數(shù)據(jù)包的全網(wǎng)廣播，縮短了路由查找過程，以達(dá)到降低路由開銷、提高路由效率的目的。 2)在VanetMobiSim和NS2仿真平臺(tái)上，選取接近現(xiàn)實(shí)場(chǎng)景的移動(dòng)模型對(duì)提出的路由算法進(jìn)行仿真，結(jié)果表明在傳輸時(shí)延，包遞送率和吞吐量三個(gè)方面比典型的地理位置路由協(xié)議具有較好的性能。 3)在已有課題研究的基礎(chǔ)上對(duì)鋰電池電動(dòng)車的車載終端進(jìn)行硬件和軟件的設(shè)計(jì)，分別從車輛節(jié)點(diǎn)和錨節(jié)點(diǎn)予以介紹，給出了體系結(jié)構(gòu)圖、部分電路及通信協(xié)議流程圖。最后設(shè)計(jì)鋰電池電動(dòng)自行車的實(shí)驗(yàn)方案，并在捷奧比公司進(jìn)行應(yīng)用測(cè)試。
[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.
