With the advancement of wireless technologies and sensing methodologies, many studies
have shown the success of re-using wireless signals (eg, WiFi) to sense human activities …

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

In the last decade, the research on and the technology for outdoor tracking have seen an
explosion of advances. It is expected that in the near future, we will witness similar trends for …

We present RF-Capture, a system that captures the human figure--ie, a coarse skeleton--
through a wall. RF-Capture tracks the 3D positions of a person's limbs and body parts even …

We have recently witnessed the emergence of RF-based indoor localization systems that
can track user motion without requiring the user to hold or wear any device. These systems …

Device-free localization of people and objects indoors not equipped with radios is playing a
critical role in many emerging applications. This paper presents an accurate model-based …

Radio frequency based device-free passive (DfP) localization techniques have shown great
potentials in localizing individual human subjects, without requiring them to carry any radio …

Through-wall tracking has gained a lot of attentions in civilian applications recently. Many
applications would benefit from such device-free tracking, eg elderly people surveillance …

RF sensor networks are wireless networks that can localize and track people (or targets)
without needing them to carry or wear any electronic device. They use the change in the …

A common technical difficulty in device-free localization and tracking (DFLT) with a wireless
sensor network is that the change of the received signal strength (RSS) of the link often …
