This paper describes research towards a system for locating wireless nodes in a home
environment requiring merely a single access point. The only sensor reading used for the …

Fingerprinting based localisation systems rely on taking a radio map of the environment and
determine the position of the device by comparing this map to its current measurements …

The proliferation of mobile computing devices and local-area wireless networks has fostered
a growing interest in location-aware systems and services. A key requirement for enabling …

WLAN indoor location that is based on received signal strength indication (RSSI) technique
needs extensive calibration to build a signal fingerprint. Re-calibration is also needed if …

We present algorithms for estimating the location of stationary and mobile users based on
heterogeneous indoor RF technologies. We propose two location algorithms, selective …

In this paper, we study issues associated with the implementation of a real-time WiFi
localization system for an indoor environment. This system utilizes smart antennas to receive …

Recent advances in pervasive computing and mobile technology have enabled accurate
location and activity tracking of users wearing wireless devices indoors, where GPS isn't …

Positioning within a local area refers to technology whereby each node is self-aware of its
position. Based on empirical study, this paper proposes an enhancement to the path loss …

When estimating the location of WiFi access points (AP) in an anonymous environment, the
required parameters of the radio propagation model are not readily obtainable. This letter …

We investigate the impact of landmark placement on localization performance using a
combination of analytic and experimental analysis. For our analysis, we have derived an …
