Development of an Energy-efficient clustering scheme and study of its performance under various node distribution strategies in WSNs

Rakesh Kumar Saini

Abstract


Low-Energy Adaptive Clustering Hierarchy is one of the most popular distributed cluster-based routing protocols in wireless sensor networks. Clustering algorithm of the Low-Energy Adaptive Clustering Hierarchy is simple but offers no guarantee about even distribution of cluster heads over the network. Low-Energy Adaptive Clustering Hierarchy doesn’t ensure even node-distribution among the clusters formed as per its provision. In this paper, we propose a Enhance Low-Energy Adaptive Clustering Hierarchy (ELEACH); the scheme must be designed to be extremely energy-efficient. Here the Enhance Low-Energy Adaptive Clustering Hierarchy is supposed to achieve objective of being energy-efficient. In this paper, the modifications proposed in the existing scheme of Low-Energy Adaptive Clustering Hierarchy which are assumed to improve the energy efficiency of the WSN.Furthermore, the Enhance Low-Energy Adaptive Clustering Hierarchy (ELEACH); would be compared with Low-Energy Adaptive Clustering Hierarchy.


Keywords


Clustering methods, energy efficiency, LEACH protocol, wireless sensor networks.
