An Energy-Efficient Zoning Clustering Hierarchy for WSNs

Focused on the limited energy characteristics of routing protocol in wireless sensor networks, we propose an Energy-Efficient Zoning Clustering Hierarchy (EEZCH) algorithm based on LEACH and LEACH-C. In EEZCH, the monitoring area is divided into several zonings (clusters). The cluster head is selected by taking the residual energy of the nodes and their relative positions in the cluster into consideration. Compared with LEACH and LEACH-C, simulation results show that the present algorithm can effectively balance the energy consumption of the nodes, significantly extend the network lifetime.
