Research of Routing Protocol Based on Clustering and Directed Diffusion

Clustering algorithm is one of the main research directions in routing algorithm in wireless sensor networks.A clustering and directed diffusion routing algorithm for wireless sensor networks is proposed to solve the problem ofimbalance in energy load for clustering algorithms.Sensor nodes are divided into clusters,and the algorithm uses directed diffusion in inter-cluster.The algorithm can make the whole network energy consumption more balanced and miximize the system＇s cycle.The result of simulation shows that the algorithm is more balanced in energy load and provides longer network lifetime.
