Abstract: In order to solve the problems of reducing the network energy consumption and improving the lifetime in the study of the routing of wireless sensor networks, in the analysis of the traditional algorithm based on LEACH, aiming at clusterhead election and cluster forming ,an efficient routing protocol was proposed. In clusterhead election, the nodes consider the remaining energy of the nodes and the distance from the base station as the main factors; while forming cluster ordinary nodes consider cluster formation according to communication cost by the distance from clusterhead and the distance from base-station to the cluster-head. The Simulation  results indicate that the new algorithm has significantly performance in reducing the energy consumption of nodes and prolonging the lifetime of the network.
