Abstract :
The indoor localization method based on wireless sensor network is attractive, the problems concerning how to identify the signal propagation state in the complex indoor environment and how to mitigate the NLOS error are challenging. In this paper, we propose a novel NLOS localization method based on Tabu search. We firstly identify the propagation state based on Kalman frame. Then a Tabu search method is employed to mitigate the NLOS error. In comparison with the Kalman and robust Kalman method, simulation results show that the proposed method has higher localization accuracy.
