Abstract
Wireless Sensor Networks, are made of low-cost, low-power, small in size, and multifunctional sensor nodes. The efficient energy utilization is one of the important performance factors for wireless sensor networks survivability be-cause nodes operate with limited battery power. In this paper we propose and analyze a new approach of zone based clustering head selection algorithm for wireless sensor network of homogeneous nodes. Nodes in the network are uniformly distributed. In this clustering algorithm, network performance is improved by selecting cluster heads on the basis of the residual energy of existing cluster heads, and nearest hop distance of the node. In this paper we evaluate various performance metrics like energy consumption, network life time, number of channel heads metrics in each round and compare these with respect to random algorithm i.e. LEACH. We conclude that proposed protocol effectively extends the network lifetime without degrading the other critical overheads and perform-ance metrics.
