Improved Energy Efficient Cluster-heads Re-usability Mechanism for Wireless Sensor Network

Abstract

Wireless sensor networks (WSNs) offers a vast range of advantages to many applications by lowering their cost and reducing their overall power consumption. A WSN is an arrangement of randomly distributed devices, i.e. sensor nodes (SNs), which are interconnected having sensing capabilities to communicate and share data with some special features. Each SN is equipped with limited resources and thrown in terrain with an unconditional climate having a pre-configured set of tasks that it needs to perform. Each of deployed SN in WSN cluster faces a considerable energy issue and needs to manipulate the power consumption to increase their lifetime and make sure that they perform all the allocated tasks. Due to the unavailability of an external power source, the energy efficiency considered as one of the critical issues in WSNs. Selection of a sensor node (SN) from a wireless sensor network (WSN) cluster to serve as an aggregator or cluster head (CH), considered as an efficient method to increase the lifetime of wireless sensor network (WSN).In this paper, we are presenting the cluster head reusability scheme to enhance the lifetime of network and to reduce the average residual energy of a single WSN. The proposed algorithm is helpful in solving the problem of unbalanced energy consumption inWSNs.
