This paper presents a weighted extended Kalman filter (WEKF) for target tracking in wireless sensor networks, where the location estimation is formulated as a weighted least squares (WLS) problem by taking weights of the local estimates based on the reliability of distance estimation and the WLS problem is solved in an iterative, decentralized manner based on the WEKF. We adopt a message passing (MP)...
In this paper, we present a positioning and tracking scheme based on adaptive weighted interpolation and Kalman filtering for wireless sensor networks. The proposed positioning method formulates location estimation as a weighted least squares problem by taking weights based on the reliability of distance estimation. This method can be realized in an iterative, decentralized manner to improve both...
This paper presents algorithms for calibrating and tracking the location of a mobile terminal based on radio propagation modeling (RPM) and Kalman filtering for indoor wireless local area networks (WLANs). In this Kalman filter-based (KF-based) tracking algorithm, the observed location information is extracted from the empirical and RPM positioning methods. Not only can the proposed RPM algorithm...
This paper presents an adaptive location estimator based on radio propagation modeling and Kalman filtering for indoor wireless local area networks. In this positioning scheme, the location of a mobile terminal is extracted from the constant-velocity trajectory by linear equations and the radio propagation model by nonlinear equations. Results from simulation exhibit that the positioning error can...
