| 摘 要： | 移动自组网中,传输路径的服务质量是影响路由性能的蘑要因素.为了提高多路径路由性能,在分析AOMDV协议的基础上,提出了一个新的参数"路径服务质量度量",用来体现当前路径传输状态.基于这个参数,同时引入路径收集的思想,提出了一种摹于路径服务质量度量的AOMDV改进路由协议PQSM-AOMDV.协议综合选择节点平均连接度大,跳数少和节点平均负荷小的路径进行数据转发,以期提高路由性能.仿真结果表明:与AOMDV协议相比,该协议提高了分组投递率,减小了分组端到端时延,降低了路由发现频率.

| Abstract: | Path quality of service is one of the key factors affecting routing performance in mobile ad hoc networks.In order to improve the multi-path routing performance,a new metric "Path Quality of Service Measurement" is presented for denoting the transmission state of the path under analysis of the AOMDV protocol.Based on this metric,path collection mechanism is used to present a new routing protocol PQSM-AOMDV.This protocol comprehensively selects the path which has bigger average link count of nodes,less hop c... |
