Target Tracking with NLOS Detection and Mitigation in Wireless Sensor Networks
International Journal of Distributed Sensor Networks, 2013 RN and SSR approaches are designed to detect NLOS propagation paths in this paper. When the NLOS propagation paths are detected, an estimation approach for the NLOS range errors is proposed by using residual-error decomposition. The approach can estimate
