摘　　要：车载自组网(VANET)是移动Ad Hoc网络(MANET)技术在交通领域的应用,由于VANET独特的场景特点,需要重新评估MANET中路由协议在VANET场景下的适用程度。为了提高仿真实验结果的准确性,实现了车辆运动模型并结合西安城区卫星地图构造了逼真的城市道路场景。在场景下利用QualNet仿真平台进行了大规模的路由协议仿真实验,评估了四种典型的MANET路由协议在城市场景VANET中的适用性。结果表明,这些协议难以满足通信需求,不适合用于城市环境下车载自组网研究。Vehicular Ad hoc Network （VANET） is a new application of Mobile Ad hoc Network （MANET） in the transportation realm. When applied to VANET, routing protocols of MANET should be re - evaluated for VANETs distinctive scenario characteristics. To improve the accuracy of experiments, a vehicle mobility model is implemented to construct realistic city scenarios with the city satellite map of Xi＇an. A large - scale routing protocol simulation is performed under QualNet in this constructed city scenario and the performance of four typical routing protocols of MANET is evaluated. The results show that such protocols can not meet the needs of VANET communication and can not be applied in urban VANET research.
