A Two Hop Relay Battery Aware Mote Scheme for Energy Redeemable and Network Lifespan Improvement in WSN

Abstract

The nodes available in the market are now of miniaturized nature, also have the characteristics of low cost and power values. Wireless Sensor Network (WSN) will be a sparse network with independent points acting as energy sources. The application in WSN includes temperature sensing, sound sensing, and pressure session. The data is sent from one point to other using multi intermediate nodes. The selection of intermediate nodes will be done based on computation of trust. As the number of hops increases energy consumption will become high and this can be improved with the help of relay node which can store the data and deliver the data once destination is in its range. The selection of relay node can be done in multiple ways like random, based on meeting probability and in the proposed two hop relay battery energy aware algorithm makes use of multiple factors namely residual energy, virtual currency based data, meeting probability, security computation so that the communication can be optimized. The proposed method is also compared with several existing methods with respect to delay, energy consumption, alive nodes, dead nodes, lifetime ratio and residual energy.
