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
more &raquo; ... sues are faced by LEACH. In this paper we represent how Extended LEACH version tackled these issues. We compare Extended LEACH Protocols with original LEACH. Keywords Cluster Head (CH), Time division multiple access (TDMA), Cluster member (CM), Base Station (BS), Wireless Sensor Network (WSN). LEACH-L (Energy Balanced LEACH) LEACH-L is energy balanced advanced multi-hop cluster based routing protocol. It is only depends upon distance. In LEACH-L the optimal hop counts are assumed. When cluster heads are sited near to BS (Base Station), then they directly communicate with BS. Cluster heads communicate via multihop mode when they are sited far away from the BS, and
