摘要
从建立多条开环路由和寻找链路不相交路径两方面对按需多路径距离矢量路由协议AOMDV进行了分析,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。基于网络节点暂停时间变化的情况,设计了针对平均端到端时延、分组传送率和路由发现频率三个指标的仿真实验。NS2仿真结果表明:PAOMDV协议在平均时延、分组传送率和路由发现频率方面,都具有比AOMDV协议更优的性能。
A analysis of the Ad hoc On-demand Multipath Distance Vector routing （AOMDV） protocol was presented, considering the aspect of building multiple loop-free paths and finding link-disjoint paths. The performance of AOMDV was improved with ＂one primary and one spare＂ routing and preemptive routing, so a protocol called PAOMDV was proposed. In the case that the pause time of the nodes changed in network, this paper designed simulation experiments of which the indexes were average end-to-end delay, packet delivery ratio and routing discovery frequency. NS2 simulations show that the performance of PAOMDV is better than AOMDV in the average delay , the packet delivery ratio and routing discovery frequency.
