Balanced Cluster Size Solution to Extend Lifetime of Wireless Sensor Networks

Abstract

Clustering algorithms are considered as energy-efficient approach for resource-constraint wireless sensor networks. Traditional clustering algorithms have uneven clusters that make network load unbalanced. In this paper, a clustering approach is proposed to address this problem and it provides balanced clusters by considering thresholds for cluster formation. Simulation results show that proposed solution can offer a better network lifetime with reduction in node death rate when compared to the traditional approaches.
