Abstract: 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.

摘要： 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。
