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

Radio frequency (RF) based indoor localisation techniques have gained much attention
over the past nearly three decades. Such techniques can be classified as active and passive …

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 …

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 …

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

Timely calls for help can really make a difference for elders who suffer from falls, particularly
in private locations. Considering privacy protection and convenience for the users, in this …

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 …

Wireless sensor networks (WSNs) have shown many attractive features in a lot of real‐world
applications not only for communication but also for localization and tracking purposes. This …

Low-data-rate wireless networks can be deployed for physical intrusion detection and
localization purposes. The intrusion of a physical object (or human) will disrupt the radio …

In this paper we derive computationally-tractable approximations of the Probability
Hypothesis Density (PHD) and Cardinalized Probability Hypothesis Density (CPHD) filters …
