Research on the Routing Protocol Improvement Based on Clusters for WSN
Studies the uneven distribution of cluster head and to communicate directly with sink of clustering algorithm LEACH routing protocol in WSN,and proposes a sub-cluster routing protocol based on the method of LEACH.This algorithm selects the head of the cluster on the basic of the node residual energy and served cluster time.The heads of the cluster uses greedy algorithm to make a chain,and selects another head in this chain,and then the data of the whole network forwards to the base station after amalgamation.The MatLab simulation shows that the protocol improved can balance the node's energy consume and the lifetime of network,and it has been greatly improved compared with LEACH.
