Finding optimal placements for mobile sensors: wireless sensor network topology adjustment

This paper considers the problem of deploying mobile sensors into an existing wireless sensor network, to adjust the network topology and enhance its performance, i.e., coverage and connectivity. A key problem of constructing a location-aware system is to deploy sensors based on detection requirements and is able to reconfigure. This paper designs, implements and analyses an algorithm to deploy a few mobile sensors to cover a maximum detection area, while keeping the maximum connectivity.
