Energy Balanced Redeployment Algorithm for Heterogeneous Wireless Sensor Networks

Abstract EN

Wireless sensor networks (WSNs) have gained worldwide attention 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 and so forth.

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, less attention is paid on the heterogeneity of the node and the energy balance of the whole network during the redeployment process.

In this work, the energy balanced problems in mobile heterogeneous WSNs redeployment have been analyzed.

The virtual force algorithm with extended virtual force model is used to improve the QoS of the deployment.

Furthermore energy model is added to enhance or limit the movement of the nodes so that the energy of nodes in the whole WSNs can be balanced and the lifetime of the networks can be prolonged.

The simulation results verify the effectiveness of this proposed algorithm.
