In this paper, the authors propose some "Innovative" optimization models for Wireless Sensor Networks (WSNs). The models are chosen depending on the task the network is called to execute and they focus on the optimization of some specific performance objectives. Indeed, starting from a generic configuration, the optimal solution defines a specific sensors displacement, which allows the network to achieve high performance, in terms of energy consumption and traveled distance. Controlled mobility of the nodes is used for reaching the wanted displacement. The behavior of the proposed models has been evaluated in comparison with a distributed algorithm on the basis of an extensive computational study and by considering different scenarios.
