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: The optimal number of cluster heads is an important parameter of wireless sensor network performance. Network nodes will consume more energy if the number of cluster heads is too much or too little. This paper focuses on novel calculation m
