摘　　要：对AODV协议在不同MANET网络环境中的性能缺陷进行了研究,提出了节点闲时反向路由搜索机制和邻居节点路由监听学习机制,并进一步提出了优化的AODV路由协议O-AODV。利用O-AODV协议在MANET网络中产生多个局部路由,从而增加网络中的路由冗余度,提高路由发现的效率,加快故障路由的本地修复。仿真实验结果表明,O-AODV协议提高了分组投递率,降低了端到端延时,有效地减少了网络中的重路由开销,在大规模和拓扑变化快的网络环境中优于AODV协议。An optimized AODV routing protocol（O-AODV） which integrated RRSL mechanism（reverse route search in leisure time） and route learning mechanism was proposed.According to O-AODV,many local routes were produced in MANET and route redundancy was increased,therefore improved the efficiency of routing discovery,speeded up the lo-cal repair procedure of break routes,and decreased the overhead of route rediscovery.Simulation results indicate that O-AODV can improve packet delivery ratio and decrease the end-to-end packet delay,its performance is superior to AODV in large scale and fast changing MANET.
