Analysis of EMCA, EFNR and HEFRN Algorithm in Wireless Sensor Networks

Abstract

One of the main challenges of wireless sensor network is maximization of the lifetime of the sensor node. Since the energy efficiency determines the lifetime of a sensor node, power consumption of the sensing device should be minimized. To conserve power, sensor node should shut off the power supply when not in use. In this paper, we analyze the performance of energy efficient algorithms namely enhanced fault node regaining (EFNR) algorithm, energy – efficient mobile-sink clustering algorithm (EMCA) and a relay node routing technique to High Energy First (HEFRN) clustering algorithm.
