Much of the energy consumption takes place during wireless communication. An efficient way to reduce energy usage is to group the sensor nodes into several clusters and each individual cluster has a cluster head. The cluster head forwards the aggregated data to the base station. In distributed clustering, the cluster head changes from one node to another node based on some parameters. In most of the distributed clustering mechanisms, every sensor nodes use same amount of power for communicating with the cluster head and base station. A distributed clustering methodology, the variable power energy efficient clustering (VEEC) mechanism has been proposed. The proposed algorithm is a well distributed and energy efficient clustering algorithm which employs relay nodes, variable transmission power and single message transmission per node for cluster set-up. The performance of the proposed methodology is compared with two existing distributed clustering algorithms LEACH and HEED. The proposed methodology depicts an improvement in average communication energy and total system energy consumption. Ultimately, the overall network lifetime is much prolonged in VEEC methodology.
