Proof-of-concept real time localization system based on the UWB and the WSN technologies

In this paper, we present an experimental localization system consisting of two fused solutions. The Ultra-wideband Localization Platform based on the time difference of arrival technique provides accurate positioning in a limited indoor area. The wireless sensor network s-net® system, calculating positions with the weighted centroid localization algorithm by the use of received signal strength indication technique provides coarse localization within a whole floor. The evaluation scenario covers one of the potential system applications-asset tracking in medical facilities.
