CTTC researchers, receive a Best Paper Award at the GlobalSIP’15
CTTC researchers, M. Calvo-Fullana, J. Matamoros and C. Antón-Haro, receive a Best Paper Award at the GlobalSIP´15.
In this paper, entitled “Sensor Selection in Energy Harvesting Wireless Sensor Networks”, they propose a novel energy harvesting (EH)-aware sensor selection policy. Their goal is to minimize the distortion in the reconstruction of the underlying source subject to the causality constraints imposed by the EH process at the sensor nodes. Besides, they determine the optimal power allocation for a given sensor selection (which admits a two-dimensional directional waterﬁlling interpretation) as the solution of an ofﬂine convex optimization problem. To that aim, they propose an iterative procedure. Performance is assessed by means of simulations and a lower bound that we also establish.
