Energy-Efficient Clustering with Rotational Supporter in WSN

Abstract

The wireless sensor network is an evergreen field of research. Everywhere we are using the sensor. Since the sensors are small in size and have less amount of initial energy, the energy saving becomes highly important and challenging. Wherever we deploy these sensors, it may or may not be accessible all the time. Hence, these should be implemented with a suitable algorithm to utilize energy efficiently. We have proposed an energy-saving algorithm by reducing the overheads of the cluster head (CH). In order to assist the CH, an assistant is selected called the supporting CH (SCH). Generally, this responsibility is rotational. Most of the nodes get a chance to serve CH so that the energy utilization is uniform. Through the proposed algorithm, the lifetime of the network in creased. This proposed algorithm is simulated using NS3 simulator and proves the energy-efficient clustering and increased lifetime as compared to other algorithms without the use of SCH.
