Ad Hoc网络是一种没有固定设施的无线移动网络，动态变化的拓扑结构对路由协议的性能有着重要影响。简要介绍了DSR和AODV两种按需路由协议，接着针对网络拓扑结构的变化，以OPNET仿真工具为平台，设计了静止、慢速变化、快速变化3种仿真方案，通过分析报文投递率和平均端到端时延比较了它们的性能。仿真结果表明，在动态拓扑变化、网络负载较大时，AODV协议的综合性能优于DSR协议，更适合于节点移动速度快且网络拓扑结构频繁变化的网络。

Ad Hoc Network is a kind of wireless mobile network without fixed facilities. The structure of topology in dynamic changes has considerable effect on the performances of routing protocol agreement. The paper briefly introduces on - demand rou- ting protocols of DSR and AODV. To the change of the structure of the network topology, three kinds of simulated schemes, namely are static, changes slowly and changes swiftly, are designed in the condition that OPNET simulation tools are iaken as the platform. Their performances are analyzed through packet delivery rate and average end and its time delay when it reaches the end. The result of the simulation shows when topology is in dynamic change and network loads greater, the comprehensive per- formances of the AODV agreement transcend DSR agreement, and it is more suitable for the network whose node moves fast and the structures of the network topology change frequently.
