摘　　要：在AOMDV协议实现节点独立路径的基础上,提出一种分布式获取分集路径的优化方案AOMDV-PD。AOMDV-PD协议引入相关因子的概念,在路由回复过程中获取物理上尽可能分离的路径集,以降低并行传输时的相互干扰。NS仿真结果显示,该优化方案能够在基本不增加路由开销的同时明显地提高分组发送成功率,缩短端到端的延迟。A purely distributed multipath protocol based on AOMDV called AOMDV with path diversity（AOMDV-PD）is proposed.This scheme introduces the conception of the path correlation factor,and a distributed algorithm is designed to determine the multiple physical diversity paths during the route discovery phase.The results of NS simulation to the optimized AOMDV-PD show that the packet delivery ratio and the end-to-end delay are enhanced obviously;meanwhile the routing overhead basically is not increased.
