This paper is devoted to large-scale monotoring by using multi-hop wireless sensor networks. Environmental applications such as pollution monitoring are considered in this paper. We consider the problem of minimizing the overall energy comsuption of the network while maximizing observability, with a receding horizon control strategy. The measure of observability is defined by the transient observability gramian associated to a finite-dimensional model of the PDE governing the pollution dynamics. Some numerical results based on a realistic case study demonstrate the effectiveness of the proposed approach.
