An Energy Model for Wireless Sensor Networks

Abstract

Wireless Sensor Networks (WSNs) are being extensively used in a wide range of applications in day to day life. However, the lifetime of Sensor Nodes (SNs) is limited due to small batteries and scarce energy supply. The promising wireless recharging technology is an efficient alternative to overcome the constraint of energy supply in WSNs. The proposed technique of Joint Energy Replenishment and Load Balancing technology (J-ERLB) can reload energy in a more controlled way in comparison to existing techniques. J-ERLB requires a pre-defined trajectory to accurately recharge the static SNs by visiting the Anchor Points (APs). In this research work, the study is conducted in four directions. First of all, a study has been carried out on various recharging mechanisms to look for appropriate wireless recharging technique that can be clubbed with modified AODV to form energy efficient model for WSNs. Secondly, with a motive to extend the network lifetime, an innovative J-ERLB technique is implemented in order to maximize the network lifetime. Thirdly, the effect of various radio propagation models has been studied after its implementation with J-ERLB. The motive behind the implementation is to find out the most suitable radio propagation model for the proposed J-ERLB mechanism. Fourthly, an analysis has been performed on various topologies like: Star, Cluster, Hybrid and Ring with a motive of finding out the most appropriate topology that fits into all the requirements of J-ERLB. newline
