Abstract

The paper addresses tracking of a moving target by means of a wireless sensor network. A centralized tracking filter and procedure for selectively activating sensors around the expected target´s position are combined. Unlike selective activation methods existing in the literature, which are concerned only with the tracking accuracy, the one considered in this work attempts to tradeoff tracking performance optimization versus lifetime maximization. A performance evaluation via Monte Carlo simulations shows the effectiveness of the proposed approach.
