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

In wireless sensor networks, owing to the limitation of energy, memory, and computation, it is necessary to design the networks under the constraints. Prolonged network lifetime and reliability are the most common requirements for many wireless senso
