Abstract: This paper refers TIGER database, builds a realistic road map as simulation scene. It evaluates the applicability of three routing protocols including AODV, DSR and DSDV in Vehicular Ad-hoc NETwork(VANET) by the joint simulation of Simulation of Urban MObility(SUMO) traffic simulator and NS2 network simulation platform. Experimental results show that existing routing protocols exist the shortages of low packet transmission success, high normalized routing load and big average end-to-end delay under urban VANET environment, it can not meet the needs of existing VANET communications in urban scenarios, and needs developing new routing protocol.

Key words: Vehicular Ad-hoc NETwork(VANET), Mobile Ad-hoc NETwork(MANET) routing protocol, Simulation of Urban MObility(SUMO) traffic simulator, TIGER database

摘要： 利用TIGER数据库，构建一个实际道路地图作为仿真场景，借助SUMO交通仿真器和NS2网络仿真平台，评估ADOV、DSR、DSDR 3种路由协议在城市场景车载自组网(VANET)中的适用性。实验结果表明，上述3种协议在城市VANET环境下，存在分组传输成功率低、归一化路由负载高、平均端到端延时大的缺点，难以满足现有城市VANET的通信需求，需要开发新的路由协议。
