Three-Level Leach Protocol to Increase Lifetime of Wireless Sensor Network

Abstract

The wireless sensor network is the decentralized type of network which is deployed on the far places. Due to small size of the sensor nodes and far deployment energy consumption is the major issue of the network. The clustering is the most efficient technique which reduces energy consumption of the network. The cluster heads in the leach protocol is selected on the basis of distance and energy. The improved LEACH is the algorithm in which leader and cluster heads are selected which transmits the data to base station. In this work, the enhancements in the improved LEACH algorithm is proposed in which gateway nodes are deployed, the cluster heads will pass the information to gateway node and it will further pass information to base station. The simulation of proposed algorithm is done in MATLAB and it performs well in terms of energy dissipation.
