Localization and tracking play a key role in several applications both civilian and military. The growing needs of remote monitoring private and public areas caused a fast development of wireless and pervasive systems. In such a framework, the availability of low-power devices integrating on-board processing and wireless communication stimulated several studies in efficient collaborative signal processing algorithms for tracking purposes. Most of them are based on the exploitation of data collected by dedicated sensor or they assume the target equipped with a transmitting device.
