摘　　要：针对车载自组织网络出现的链路不稳定、数据传输效率低、路由表现不理想等问题,使用微观交通仿真工具SUMO与网络仿真模拟器NS3进行联合仿真,研究了高速公路不同交通场景下AODV和DSDV路由协议的性能。结果表明:在不同车辆数和车速下,AODV协议分组投递率和吞吐量优于DSDV协议,平均端到端时延比DSDV协议要高,但从路由协议整体性能来看,AODV路由协议并不足以适用于车载自组织网络。Aiming at the problems of link instability,low data transmission efficiency,and unsatisfactory routing performance in vehicular ad hoc network,the micro-traffic simulation tool SUMO and the network simulation simulator NS3 were used for joint simulation to study AODV and DSDV routing protocols in different traffic scenarios in the highway environment.The simulation results show that the packet delivery rate and throughput of the AODV protocol are better than those of the DSDV protocol under different vehicle node numbers and vehicle moving speeds,and the average end-to-end delay is higher than that of the DSDV protocol.However,from the perspective of the overall performance of the routing protocol,AODV routing protocol is not enough to apply to the vehicular ad hoc network.The simulation provides suggestions and references for subsequent routing protocol improvements.
