Abstract: In recent years, there has been a growing interest in wireless sensor networks. One of the major issues in wireless sensor network is developing an energy efficient routing protocol. LEACH is very effective in enhancing nodes’ lifetime from

Abstract—LEACH is a hierarchy routing protocol for WSN (wireless sensor networks), which is superior to direct communication protocol, minimum-transmission-energy protocol and static clustering protocol. owever, LEACH itself has some defects. In this

Abstract This paper talk about the communication protocol named LEACH. The protocol focuses on reducing the power consumption of wireless sensor networks, which can have significant impact on the overall energy dissipation of these networks. LEACH
