Wireless sensor networks (WSNs) are cluster of sensor nodes that co-operate together to monitor an environment or a system. It include of large number of sensor nodes, which sense and measure various physical phenomena related parameters and hand over the measured data towards the base station by making use of the neighbouring nodes acting as relay nodes.It rely on various resource constrained nodes with limited energy, range, memory and computational power it is essential to conserve battery energy so as to extend the life time of the given WSN deployment. These sensor nodes works on limited battery source, one of the factor to be consider while designing a WSNs protocol is by efficient use of available energy resources to prolong network lifetime. One of the efficient WSNs protocol is Low Energy Adaptive Cluster Hierarchy (LEACH). In this paper we present leach protocol and we use heterogeneous nodes for data transmission through the optimal path between cluster heads (CHs) and the base station (BS).In LEACH, Non-Cluster head Nodes decide to link a cluster head based on Received Signal Strength (RSS) of receiving packets from CHs.

Keywords- Wireless sensor network (WSN), LEACH protocol.
