ABSTRACT
Wireless sensor network (WSN) is a new and fast advancing technology, which is opening up many opportunities
in the field of remote sensing and data monitoring. Even though the advances in embedded systems, the energy
consumption is still open issue in WSNs. Recently there has been growing interest in the applications of sensor
networks. The radio transmission and reception consumes a lot of energy, one of the important issues in wireless
sensor network is the inherent limited battery power within network sensor nodes. Since sensors are generally
constrained in on-board energy supply, efficient management of the network is crucial in extending the life of the
sensor. In addition to maximizing the lifespan of sensor nodes, it is preferable to distribute the energy dissipated
throughout the wireless sensor network in order to maximize overall network performance. In this paper, the
focus is mainly driven over the survey of the hierarchical cluster-based available routings in Wireless Sensor
Network for energy consumption. Low-Energy Adaptive Clustering Hierarchy (LEACH) protocol is one of the
best hierarchical protocols utilizing the probabilistic model to manage the energy consumption of WSN.
Simulation results, shows the energy consumption over time of three nodes with distance to the Base Station.
