LEACH: IMPLEMENTATION OF ROUTING PROTOCOLS IN WIRELESS SENSOR NETWORKS

Abstract

Wireless Sensor Networks is an active research area in today’s computer science & Engineering and telecommunication field. The Wireless Sensor Networks consists of a number of tiny sensor nodes to watch corporeal or physical and ecological situation, such as temperature, vibration, pressure, sound or motion, and then collectively send this information to a central computing system, called the base station or sink. Different routing protocols govern the movement of this information. Broadly the routing protocols can be classified as at-based routing, hierarchical-based routing, and location based routing. LEACH (Low Energy Adaptive Clustering Hierarchy) is a hierarchical-based routing protocol which uses random rotation of the nodes required to be the cluster-heads to evenly distribute energy consumption in the network.
