COOPERATIVE LOCALIZATION USING EFFICIENT KALMAN FILTERING FOR MOBILE WIRELESS SENSOR NETWORKS

by Hadi Jamali Rad, Toon Van Waterschoot, Geert Leus
"... We consider the problem of cooperative localization in mobile wireless sensor networks (WSNs). To be able to continuously localize the mobile network, we propose to exploit the knowledge of the location of the anchor nodes to linearize the nonlinear distance measurements with respect to the location ..."

to the location of the unknown nodes. Based on this linearized measurement model, we estimate the location of the unknown nodes using a Kalman filter (KF) instead of a suboptimal extended KF (EKF) and try to estimate the corresponding unknown measurement noise covariance matrix using an iterative process

Towards self-organizing Kalman filters

by J Sijs , Z Papp - In Proceedings of the 15th International Conference on Information Fusion (FUSION), Singapore, 9–12 , 2012
"... Abstract-Distributed Kalman filtering is an important signal processing method for state estimation in large-scale sensor networks. However, existing solutions do not account for unforeseen events that are likely to occur and thus dramatically changing the operational conditions (e.g. node failure, ..."

. Such distributed Kalman filters typically process the sensor measurements locally at each node rather then communicating them to a single, central node. Characteristic approaches to distributed Kalman filtering are presented in [1]-[4] and the references therein. The proposed methods perform a modified Kalman

Location Tracking in Wireless Local Area Networks with Adaptive Radio Maps

by A. Kushki, K. N. Plataniotis, A. N. Venetsanopoulos - Proc. IEEE Int’l Conf. Acoustics, Speech, and Signal Processing (ICASSP , 2006
"... This paper proposes a dynamic MMSE estimator for tracking mobile users in indoor Wireless Local Area Networks (WLAN) based on Received Signal Strength (RSS). The method uses a training-based static estimate obtained by an adaptive kernel density estimator as the input into a Kalman Filter. Predictio ..."
