Cluster Head Selection for Equal Cluster Size in Wireless Sensor Networks

The goal of wireless sensor networks is to collect sensing data on a specific region using wireless communication. The sink node gathers all local sensing data, processes them, and transmits them to users who use sensor networks. Generally, sensor nodes are low-cost, low power devices with limited sensing, computation and wireless communication capabilities. A sensor network applies to multi-hop communication on a large-scale network. As neighboring sensor nodes have similar data, clustering is an effective technique for dasiadata-aggregationpsila. In the multi-hop based cluster formation technique, it is necessary that the number of cluster member nodes should be distributed equally due to the balance of cluster formation. Therefore, this paper proposes a method of cluster head selection to form equal cluster sizes in wireless sensor networks.
