Abstract :
Localization in distributed Ultra-Wideband sensor networks is an important area that attracts significant research interest. In this paper, main sources of errors in a realistic indoor environment of range-based localization are analyzed and a novel UWB localization approach is proposed which considers ranging, location estimation, NLOS identification and tracking. The performance of it is evaluated by computer simulation in an assumed indoor scenario with different LOS/NLOS situations.
