Efficient LEACH algorithm based on energy equalization

Abstract： LEACH routing protocol is a classical clustering routing method in wireless sensor networks. However, in severely limited wireless networks, high power consumption and short lifetime of nodes seriously affect network performance. In this paper, an improved efficient LEACH-X protocol based on energy balance is proposed. By joining the optimal number of cluster head, the surplus energy correction factor is put forward. Considering the residual energy of nodes,the number of cluster head during the period and density factor, and partitioning the deployment area， the cluster head election threshold function is modified by adjusting the weight of the distance factor gain parameters for the region.Then, the second competition is in progress and ultimately the cluster head is selectd, so as to reduce the energy consumption of nodes, the survival time of WSN can be extended to some extent. Simulation results show that compared with the traditional LEACH protocol, the LEACH-X protocol reduces the network energy consumption and prolongs the network lifetime.
