Abstract

Energy conserving optimization is of chief concern while scheming a wireless sensor network (WSN) as most of the sensor nodes are furnished with limited power supply. In this paper, we focus on minimizing energy consumption and maximizing network lifetime in three-tiered network architecture. For this obvious goal, clustering techniques are a boon with a hierarchical arrangement to boost the performance of the network as well as reduce the consumption of energy. For a distantly located base station, a sensor node will require large amount of energy for the single hop communication. As a result eventual exhaustion of node energy and hence, shortened network lifetime and also network failure. To overcome this unavoidable situation, relay nodes are being used to exploit the benefits of multihop transmission to save the energy. In this work, the proposed method for relaying is based on genetic algorithm (GA) approach in terms of node’s initial energy, residual energy, distance to base station and the probability of getting selected as cluster head. It is designed to assure minimum energy cost as well as save the nodes with comparatively low residual energy. Finally, simulations have been performed to prove the helpfulness of the proposed approach.Cite this Article Tirkey A, Kakkar D.
