Research on CDPMR Routing Algorithm in Wireless Sensor Networks

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.
