Active received signal strength (RSS)-based localization systems estimate the location of a device-equipped target by using the RSS measurements between the target's device and a set of known-location nodes. To improve the accuracy of such systems, additional information from other devices such as inertial sensors or antenna arrays have been used at the(More)
Device-free localization (DFL) is the method of determining an uncooperative target's location by using the shadowing induced by the target on the radio links crossing through the wireless network's deployment area. Most DFL schemes require high memory and computing resources for accurate tracking performance, and thus may not be suitable for(More)
In this paper, geometry-based algorithms for device-free localization (DFL) of a single target are proposed. The algorithms exploit the change in attenuation caused by the device-free target on radio links passing through the deployment area. By solving for the intersections of some of the attenuated links and taking the centroid of the intersection points,(More)
