LEACH Algorithm Based on Energy Consumption Equilibrium

Aiming at the problem of the network lifetime of wireless sensor network (WSN), this paper presents an optimization algorithm based on LEACH algorithm. In the optimization algorithm, some nodes in the vicinity of the base station connect to the base station directly, we extend the network life by increasing the energy consumption of the base station to share the energy consumption with the network; after the cluster is established, we elect secondary cluster head from the cluster, secondary cluster head collect information and pass the information to the cluster head, and the cluster head pass the information to the base station. Proved by simulation, this algorithm can extend approximately twice the life cycle compared with the traditional algorithm LEACH and DEEC.
