In order to prolong the network lifetime,energy-efficient protocols should be designed to adapt the characteristic of wireless sensor networks.Clustering algorithm is a kind of key technique used to reduce energy consumption,which can increase network scala-bility and lifetime.The LEACH protocol is low power and adaptive lamination route algorithm.However,the original algorithm of the LEACH is based on the proposal,which every node send it's datum to the cluster heads by just one hop;then,these cluster heads send their gathered datum to base station by one hop too .Just because of it's characteristic,the old algorithm is very wasting energy and can lead some cluster heads consume more energy.In order to solve that problem,a new protocol adopt cluster heads multi-hop algorithm based on LEACH is proposed.In this protocol an optimal path is formed among cluster heads which lead to path.Experimental result indicates that the new algorithm is very energy-efficient,and it can prolong the lifetime of the sensor network.
