Abstract: One of the key points of network routing design is power management.The paper summarizes the current transmitting routing model in wireless sensor networks，and finds that although the LEACH protocol is low power and adaptive lamination route algorithm，it might lead to overload of some cluster head nodes.Clustering algorithm is a kind of key technique used to reduce energy consumption.This article proposes a multi-hop routing improved algorithm based on the LEACH algorithm，and taking the optimization of the number of cluster heads into account，it can reduce energy consumption and prolong the lifetime of sense network through the use of multi-hop algorithm among cluster heads.Experimental result indicates it is effective.
