A Cluster Based Routing Protocol in Wireless Sensor Network for Energy Consumption

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.
