Based on LEACH Protocol, an improved LEACH Protocol (LEACH-H) is proposed based on Genetic Algorithm (GA) in this paper. The weight values of the three influencing factors--the current residual energy of nodes, the number of the neighbor nodes and the distance between nodes and base station are used as its optimization variable. The maximum lifetime of the(More)
