Research on CDPMR Routing Algorithm in Wireless Sensor Networks

在无线传感器网络路由协议中,分簇路由具有扩展性强、数据融合简单、能量利用高效等特点。基于一些分簇算法和多路径路由算法,提出基于簇指挥路径的多路径路由算法(CDPMR)。仿真结果表明,与其他路由算法相比,CDPMR扩展性好,控制负载低,网络拓扑稳定,能减少网络重构开销带来的通信代价,有利于均衡网络能量消耗,延长网络生命周期。

In wireless sensor networks routing protocol,cluster-based routing has the characters of good expansibility,simple data aggregation,energy efficiency.A Cluster Director Path Multi-path Routing algorithm（CDPMR） is proposed on analysis of other multi-path routing algorithm.Simulation shows that CDPMR can be more extendable,lower overload and good stability than other multi-path routing algorithms.Comparing to other cluster-based routing algorithms,the algorithm can get more steady topology,reduce communication cost of rebuilding, and can balance network＇s energy consume, prolong the networks life.
