—This paper introduces a real-time localization system (RTLS) using efficient multiple propagation models to compensate for the drawback of the received signal strength technique. The RTLS is implemented on an active RFID system and uses received signal strength measurements and reference tags for ranging. The RTLS is implemented purely in software that(More)
—A comparison between two different systems for smart space localization is presented. A smart space implemented at the University of Nebraska-Lincoln was designed for automated and intelligent assistance for elderly and disabled people, and also for astronauts in space. Localization is a critical component of the smart space since it provides the system(More)
