摘　　要：针对目前移动自组网路由协议的研究,介绍了Ad hoc网络路由协议设计的目标,对无线自组网Ad hoc的按需距离向量协议AODV进行了研究,通过仿真分析了不同网络规模、不同的节点移动速度、源节点不同发包率对AODV的性能的影响,结果证明随着网络规模的扩大,路由开销、丢包率都有所增加;AODV协议对20米/秒以下的网络拓扑变化的适应性较好;发包率对AODV性能的影响比较明显,当发包率超过20包/秒时,网络性能恶化。In view of the current research of mobile Ad hoc network routing protocol, introduces the designing goal of routing protocols, researched AODV routing protocol working principle, through the OPNET simulation, analyze AODV performance on different size of networks, different speeds of the mobile nodes and different packet inter-arrival time of the source nodes. The results prove that with the expansion of the network size,load and data dropped has inereased;AODV protocol for the adaptive changes in network topology better, packet inter-arrival time on the performance of more obvious,it will deteriorate the network performance when the packet inter-arrival time of lower than 0. 05 s.
