Enhancing Lifetime of Wireless Sensor Networks Using LEACH Protocol

Abstract

Wireless sensor networks (WSNs) are considered as one of the most important and essential technologies in today's environment. WSNs sustain a bridge between the real physical and virtual worlds. Sensors nodes can be deployed in hostile environment where there is no access of human beings. However, sensor nodes rely on battery power and it becomes a difficult task to replace the battery in such an environment. Hence, in light of this it becomes very important task to improve the networks energy. To overcome this problem, a routing protocol was proposed. This is known as Low Energy Adaptive Clustering Hierarchy (LEACH). The implementation of this protocol is done by the use of MATLAB. This document focuses on enhancing the lifetime of the sensor node in Wireless Sensor Networks using the LEACH protocol.
