Dynamic sensor networks: an approach to optimal dynamic field coverage

In the paper a solution to the sensor network coverage problem is proposed, based on the usage of moving sensors that allow a larger fields coverage using a smaller number of devices. The problem than moves from the optimal allocation of fixed or almost fixed sensors to the determination of optimal trajectories for moving sensors. In the paper a suboptimal solution obtained from the sampled optimal problem is given. First, in order to put in evidence the formulation and the solution approach to the optimization problem, a single moving sensor has been addressed. Then, the results for multisensor systems are shown. Some simulation results are also reported to show the behavior of the sensors network.
