Lifetime Maximization of Wireless Sensor Network using Unequal Clustering

Abstract

Wireless Sensor Network (WSN) is a set of self-regulating sensors which are minute devices and it has limited battery power and a reduced amount of computing ability. The nodes of the sensors dispensed arbitrarily or physically in the sensing region to log the environmental constraints of a region meant to notify a specific destination called BS (BS). The organization of WSN into a set of clustering enabling effective exploitation of restricted energy resources of the placed nodes. But, the issue of uneven energy utilization exists and is related to the localization of a specific node in WSN. When the network undergo organization into different clusters where few significant nodes plays a vital role of cluster head (CH) for network management. In some cases, the clusters are organized in an unequal form called Unequal Clustering Size (UCS) to organize the nodes, results in consistent energy utilization and maximized lifetime of WSN. Besides, it is evident that it offers consistent energy utilization in a homogeneous way.
