The paper presents the Vehicular Ad hoc Networks and two typical routing protocols: the table-driven routing protocol (DSDV) and the Ad hoc On-demand routing protocol (AODV) in mobile ad hoc networks. And a practical mobility model is used to enable the simulation experiment more veritable. Then NS2, a network simulation tool, is implemented to simulate the two typical routing protocols in ad hoc networks based on Linux,and the simulation results are analyzed and compared. The result is that the AODV and DSDV routing protocols are not suitable for vehicular ad hoc networks, so designing a proper protocol is an urgent problem.%本文简要介绍了车载自组织网络和移动自组织网络中两个典型的路由协议:表驱动路由协议DSDV和按需路由协议AODV;还介绍了一个实用的移动模型,使仿真实验更加接近现实.在Linux下使用网络仿真工具NS2对这两个典型协议进行仿真,并对仿真结果进行分析比较和性能评价,得出:AODV和DSDV协议都不太适用于车辆自组织网络,所以设计适合车辆网路的协议是急需解决的问题.
