An efficient cluster head selection strategy for provisioning fairness in wireless sensor networks

To select fair and balanced cluster head for cross layer protocol in wireless sensor network, a novel scheme is proposed in this paper. Because LEACH-C and its most of the variants select cluster head by considering energy and distance as a crucial parameter, it can reduce energy consumption of nodes but fail to create balanced cluster. According to the requirement of fair CH selection, we consider residual energy, number of neighbor nodes and one hop neighbor information. The proposed algorithm not only save significant amount of energy but also cover every region of the sensing area in a balanced manner. We evaluate our proposed protocol with two recent clustering approach, one is distributed and another is centralized approach. Matlab simulation result shows that the significant performance improvement over the related schemes achieved by proposed protocol in terms of First Node Death (FND), Last Node Death (LND) and energy consumption.
