Wireless Sensor Networks (WSNs) are severely resource constrained, especially in the aspect of power supply. How to effectively manage power consumption so that the lifetime of a WSN can be maximized is a central topic for research in WSN routing protocols. As an attractive WSN routing protocol, LEACHCl~2] has been widely accepted for its energy efficiency and simplicity. Based on LEACH, we propose a new routing protocol MELEACH (More Energy-efficient LEACH), which has a better performance on energy efficiency without losing the advantages of LEACH. MELEACH improves LEACH by further reducing the mean transmission distance and improving the load balance between sensor nodes, Our analysis and simulation results have shown that the lifetime of a WSN running in MELEACH is at least 50 % longer than that running in LEACH.
