Abstract

In this paper, we propose a zone-based clustering method to balance the amount of energy consumptions over all sensor nodes in the wireless sensor network field. In our method, a network field is divided into several zones with two types of shape: arc and square. And, the number of clusterheads selected in each zone is determined depending on its area. These contribute to distributing clusterheads evenly over the network field. Simulation results show that our zone method can outperform LEACH and PEGASIS in terms of network lifetime and connectivity.
