In order to solve the problem of LEACH Algorithm can not guarantee the larger residual energy node absolutely ware elected as cluster head,and it consumes large amounts of energy for double counting of cluster head election,at the same time,the influence of the node distance for cluster head election is not included.The improved LEACH algorithm has solved the problems veηwell, it makes a use of cluster heads projection to decrease the number of cluster competition by combining with the optimal cluster head selection algorithm,which can red...
