Energy consumption is most important in wireless sensor network. Due to the limitation of power and memory size, the router protocol of wireless sensor networks must maintain small router information and reduce the power usage as much as possible. LEACH (LOW-Energy Adaptive Clustering Hierarchy) protocol is a popular protocol for wireless sensor network, but energy consumption still not satisfied. In this paper, an improved LEACH algorithm is proposed to overcome some disadvantages of conventional LEACH protocol. In the improved LEACH algorithm, the node remaining energy is considered to selection of cluster head, MTE(Minimum Transmission Energy) routing is used to translation of the data. Simulation results show that the life cycle of network is extended and energy consuming of node is saved than that of conventional LEACH algorithm.
