The recent developments in high speed computing electronics and wireless communications have created an opportunity for the advancement in power efficient and low cost Wireless Sensor Networks (WSNs) with diverse areas of applications. But wireless sensor nodes are limited in power. To extend the network lifetime of the nodes in the WSN, efficient power utilization is an important variable to be optimized. In this paper, a routing protocol called Grid Clustering Hierarchy (GCH) that provides an efficient energy management for WSNs is proposed. This protocol divides the network into a variable number of virtual grids based on the current average energy of the network to create optimum clusters in terms of energy consumption. Using a standard radio energy dissipation model that is commonly used for simulation of WSNs, GCH is simulated and its performance is compared with a well-known routing protocol for WSNs named LEACH.
