Clustering Approach for Enhancing Network Energy using LEACH Protocol in WSN

Ankit Gupta, Monika Goyal, Sangeeta Malik

Abstract


A wireless sensor network which consists of a group of sensor nodes enables the monitoring of a variety of environments for applications. In WSNs, it is very critical to operate sensor network for a long time. In wireless sensor networks, data fusion helps to reduce the amount of data transmitted between sensor nodes and the base station. The LEACH (Low-Energy Adaptive Clustering Hierarchy) [1] protocol is an elegant solution to this data collection problem, where a small number of clusters are formed in a self-organized manner. In this research paper we proposed an algorithm which is modified version of LEACH and using MATLAB simulator we evaluated the performance of improved protocol in terms of network lifetime, number of dead nodes, and number of alive nodes in comparison with existing protocol.
