In the paper, the existing wireless sensor network routing protocol classification and comparative studies, then A targeted selection of typical clustering routing protocol Low Energy Adaptive Clustering Hierarchy (LEACH) protocol for the study, points Insufficient analysis of LEACH, and on this basis to select the optimal number of cluster head LEACH protocol, Selected on the basis of cluster head node, communication between clusters, cluster head node in a distributed fashion to improve "change After the agreement into improving the selection criteria LEACH cluster head, so that the cluster head node distributed more evenly, avoiding Free a single node excessive energy consumption. Finally, the improved LEACH protocol is added by way of randomly selected based on the energy value of closed Residual nodes on MATLAB simulation platform, the simulation results show that adding the residual section Point effectively extending the network life time improves the efficiency of the network.
