Abstract

Wireless sensor networks (WSNs) have shown many attractive features in a lot ofreal‐world applications that motivate their rapid and wide diffusion. One of the mostchallenging topics when dealing with WSNs is the localization and tracking of objects frommeasurements collected by the nodes themselves. Once distributed in a region without theknowledge of their positions, the nodes actively take part in the localization of the networkas well as to the detection and monitoring of the presence and movements of targetslying within the sensed area. This paper reviews state‐of‐the‐art systems and approachesdeveloped for WSN‐based localization and tracking of active as well as passive targets.The main focus is on systems that exploit the strength of the received signal, always availableat the WSN nodes, without ad hoc or additional hardware. Recent strategies for WSN‐based imaging are discussed as well.
