Localization of Mobile Nodes in Wireless Networks With Correlated in Time Measurement Noise

Wireless Sensor Networks (WSNs) are widely used in applications like location monitoring, object tracking and decision making systems. Movement patterns of mobile sensor nodes play an important role in such systems. This paper is aimed at simultaneous localization of mobile nodes. This is done based on RSSIs (Received Signal Strength Indicators) with correlated in time measurement noises. The authors proposed a framework with two multi model auxiliary particle filters. The first one is with a noise augmented state vector while the second one is to implement noise decorrelation.
