The “Smart World” envisioned by technology will be achieved by the penetration of
intelligence into ubiquitous things, including physical objects, cyber-entities, social-elements …

The requirement of active localization techniques to attach a hardware device to the targets
that need to be located can be difficult or even impossible for certain applications. For this …

Radio-frequency (RF) tomography is the method of tracking targets using received signal-
strength (RSS) measurements for RF transmissions between multiple sensor nodes. When …

This paper presents and evaluates a method for simultaneously tracking a target while
localizing the sensor nodes of a passive device-free tracking system. The system uses …

RSS-based device-free localization (DFL) monitors changes in the received signal strength
(RSS) measured by a network of static wireless nodes to locate and track people without …

Received signal strength based device-free localization applications utilize a model that
relates the measurements to position of the wireless sensors and person, and the underlying …

Device-free wireless localization (DFL) is a technique that can locate a target by analyzing
its shadowing effect on wireless links, which causes the variation of link measurements …

Radio tomographic imaging systems use received signal strength measurements between
static wireless sensors to image the changes in the radio propagation environment in the …

Device-free localization (DFL) based on received signal strength (RSS) measurements
functions by measuring RSS variation due to the presence of the target. The accuracy of a …

Received signal strength based radio tomographic imaging is a popular device-free indoor
localization method which reconstructs the spatial loss field of the environment using …
