Performance analysis of Energy consumption in WSN with Four GW using Zone Clustering routing protocol

Abstract

Wireless Sensor Network (WSN) is widely used for monitoring and gathering data in an autonomous fashion. Since sensors are small and power constrained devices, it is the most important to minimize the energy consumption. We propose energy efficient zone routing protocol with multi-gateway for enhancing life time performance of wireless sensor networks. In this paper, two types of sensor nodes, i.e., advanced and normal nodes are used. Advance nodes are having more energy than normal nodes. The advanced nodes are selected as cluster head based on its energy and node degree in the network. Normal nodes are used for sensing and data forwarding. Using multi-gateway we have reduced communication cost among sensor nodes used for transmitting and receiving the messages for cluster head selection. Simulation results show that by selecting the optimum position of cluster head on the basis of density, the consumption of energy for communication is minimized. It also increases the overall lifetime compared with the existing schemes. In this paper we are observing the energy consumption in WSN with four GW using zone clustering routing protocol.
