Prioritized Mobile Node Deployment to Enhance the Lifetime of Wireless Sensor Network
2017
In Wireless Sensor Networks, the available energy of the prevailing sensor nodes is limited and is difficult to replenish. It is very critical to supervise the available energy. In Mission Critical Surveillance application, due to node’s battery depletion, coverage hole may be created. Hole at Critical Point (CP) leads to the degradation of performance of overall network. It is merely impossible, to redeploy sensor nodes or to recharge the battery while monitoring. The proposed Energy Balanced-Dynamic Deployment Optimization approach, positions the self deployable mobile sensors towards CP according to its available Energy Density. This balances the Energy Density of the network thereby increasing the Reliable Lifetime. The simulation results show the effectiveness of the approach in terms of the balanced Energy Density around CPs with less mobility.
