摘　　要：车载自组织网络具有拓扑变化频繁、链路易断等特性,针对AODV路由协议存在传输延迟长、路由开销大等问题,本文基于车辆分簇思想对AODV路由协议进行改进,以数据传输延迟为优化目标得出源节点到目的节点间的最小延迟路径。通过对高速公路网络场景的仿真分析,结果表明,改进后协议可有效降低数据传输延迟及网络开销,提高分组投递率。Vehicle Ad-hoc Network(VANET)has the characteristics of frequent topology changes and fragile links and so on.Considering the problems of long transmission delay and large routing overhead in the AODV routing protocol,this paper improves the AODV routing protocol based on the idea of vehicle clustering,and obtains the minimum delay path between source node and destination node with the data transmission delay as the optimization target.Through the simulation analysis of the highway network scene,the results show that the improved protocol can effectively reduce the data transmission delay and network overhead,and improve the packet delivery rate.
