Tracking a target is a fundamental and crucial problem in wireless sensor networks. It is well known that Non-Line-Of-Sight (NLOS) propagation will significantly degrade the tracking accuracy if its effects are ignored. In this paper, a Line-Of-Sight (LOS) identification approach for range-based tracking systems is developed to discard the NLOS measurements. Based on Lp-norm LOS identification strategy, a novel target tracking method is devised with the use of cost-reference particle filter, which does not require the knowledge of the measurement noise distribution.
