Energy Balanced Virtual Force-Based Approach for Mobile WSNs

Wireless Sensor Networks (WSNs) have gained worldwide attentions in recent years. Since WSNs can be conveniently deployed to monitor a given field of interest, they have been considered as a great long-term economic potential for military, environmental, and scientific applications etc. One of the most active areas of research in WSNs is the coverage which is one of the most essential functions to guarantee quality of service (QoS) in WSNs. However, little attention is pied on the energy balance of the whole network. In this work, the energy balanced problems in mobile WSNs redeployment have been analyzed. The virtual force algorithm with extend virtual force model is used to improve the QoS of the deployment. And energy model is added to enhance or limit the movement the nodes so that the energy of the whole WSNs can be balanced and the lifetime of the network can be prolong. The simulation results verify the effectiveness of this proposed algorithm.
