Energy Efficient balanced Cluster Size Solution to Extend Lifetime of Wireless Sensor Networks

Grouping sensor nodes into clusters has been widely adopted by the research community to achieve high energy efficiency and prolong network lifetime in large scale WSN environments. Clustering algorithms are considered as energy efficient approach for resource constraint wireless sensor networks. Traditional clustering algorithms results cluster formation with uneven clusters that make network load unbalanced. In this paper, a clustering algorithm is designed to identify this problem and it results balanced cluster size solution by considering thresholds for cluster formation. Simulation results indicate that current solution can offer a better network lifetime with reduction in node death rate in comparison with existing approaches.
