| 摘 要： | 对AOMDV协议进行了分析，指出了协议存在的不足，利用“一主一备”式路由和抢先式路由对其进行了改进，提出了PAOMDV协议。对NS2（Network Simulator Version2）的分裂对象模型进行了分析，基于NS2实现了AOMDV及PAOMDV路由协议的扩展与仿真。仿真结果表明：在相同的网络环境下，与AOMDV协议相比，PAOMDV协议减少了平均时延、降低了路由发现频率、提高了分组传送率。

| Abstract: | Based on the analysis of Ad hoc On-demand Multipath Distance Vector routing(AOMDV) protocol,its defect is pointed out in this paper,and we propose a PAOMDV protocol as a result of improving the AOMDV withone primary plus one sparerouting and pre-emptive routing strategies.The Splitting Object Model of NS2 is analysed.Based on NS2 we implement an extension in NS2 for the simulation of AOMDV and PAOMDV protocols.Simulation results show that PAOMDV protocol has lower average delay and routing discovery frequen... |
