The document discusses target tracking in mobile sensor networks. It describes the components of a mobile sensor network for tracking, including sensors, mobiles, monitors and networks. It analyzes existing target tracking systems and their disadvantages in assuming weak adversary models. The proposed system aims to improve spatial resolution for localizing targets by considering moving targets and mobile sensors. It describes the target tracking process carried out by servers, commanders and trackers. Potential applications are in mobile navigation, military operations, wireless communications and criminal investigations. Mobility can be exploited to obtain better spatial resolution for target tracking.
