Accurate ranging and localization in non-line-of-sight (NLOS) conditions is an open
research problem. In indoor environments, NLOS causes ranging and location errors due to …

On the positioning accuracy, the geometric distribution of anchor nodes in wireless sensor
networks has notable impacts. To select the optimum node combination, conventional …

Accurate indoor localization remains a significant challenge, primarily due to multipath and
non-line-of-sight (NLoS) propagation conditions in complex indoor environments. Traditional …

In wireless localization systems, the performance enhancement of location estimation is an
important goal. In recent years, different positioning systems using an ultra‐wide band …

Human activity recognition (HAR) has become an increasingly popular application of
machine learning across a range of domains. Typically the HAR task that a machine …

The performance of a range-based indoor positioning system is severely degraded by non-
line-of-sight (NLOS) propagation due to the offsets in range measurements (ie, NLOS …

For location-based applications, wireless systems in an indoor environment often operate
under non-lineof-sight (NLOS) conditions that may cause ranging errors. A promising …

Emergency first response teams during operations expend much time to communicate their
current location and status with their leader over noisy radio communication systems. We …

Indoor positioning systems have been widely studied in the last decade due to the need of
humans for them especially in the large building such as malls, airports, hospitals... etc. Still …
