摘　　要：针对AOMDV与SMR协议的工作机制,利用NS-2仿真平台对AOMDV与SMR协议进行不同运动场景的仿真比较.仿真结果表明,对于中低速动态的MANET网络环境,SMR协议以一定的路由开销为代价,能有效改善网络端到端时延与分组投递率性能;对于高速动态的MANET网络环境,AOMDV协议具有更好的链路容错性能和更有效的恢复机制.Aiming at the on-demand multi-path routing mechanism of AOMDV and SMR routing protocol,the performance of AOMDV protocol is simulated compared with SMR in the case of given scenario by NS-2.The results show that,in MANET environment with rapidly and changing topology,with AOMDV,network has better performance;and in environment with slowly and changing topology,packet delivery ratio and end to end delay are improved in SMR protocol at the price of the limited routing load.
