摘　　要：简要介绍了Ad Hoc网络的定义、网络的关键技术、典型路由协议、面临的一系列问题以及发展前景。然后基于Ad Hoc网络的网络环境,对AODV路由协议进行了详细分析,并通过网络仿真软件NS—2比较、分析了AODV、DSDV、DSR等路由协议在端到端平均延迟、分组投递率、路由开销等方面的网络性能。最后对几种路由协议的性能上进行了比较与归纳,通过对AODV协议的分析与测试,得出了AODV在分组投递率和路由开销方面明显优于DS-DV、DSR协议的结论。Ad Hoc network＇s definition,key technical,typical routing protocol,faced problems and development prospect were introduced.Then based on Ad Hoc net＇s network environment,the AODV route protocol was detailedly analyzed,and the performances of route protocol such as AODV,DSDV and DSR,in the end-to-end average delay,route expenses,packet delivery ratio were compared and analyzed by network simulation software NS-2.Through-the comparison and extrapolation of the route protocols,and the test and analysis on AODV protocol,it was concluded that in the aspects of packet delivery ratio and route expenses,AODV protocol is obviously superior to DSDV and DSR protocols.
