LEACH and Extended LEACH Protocols in Wireless Sensor Network-A Survey

Abstract

Wireless Sensor Network is collection of wireless sensor nodes in which routing protocol is most challenging issue. Sensors have limited battery power. Battery extends the lifetime of sensor nodes. Energy utilization is one of the most important considerations. There are various routing techniques which increase lifetime of battery. One of the most energy efficient clustering routing protocols is LEACH. In this survey paper we represent LEACH & Extended version of LEACH routing protocol. Some issues are faced by LEACH. In this paper we represent how Extended LEACH version tackled these issues. We compare Extended LEACH Protocols with original LEACH.
