Abstract
In this paper, an adaptive filter is presented for position-tracking of a mobile node using WLAN Received Signal Strength Indicator (RSSI). To take the dynamics of the mobile node into consideration, the presented filter is expressed based on an Interacting Multiple Model (IMM) filter. In indoor environment, Additional Signal Attenuation Error (ASAE) occurs due to several obstacles such as wall, furniture, etc. It causes large positioning error. The presented filter includes an ASAE mitigation function of individual channels. In the simulation test, it shows that the presented filter can provide an accurate position-tracking solution for a mobile node using WLAN RSSI in indoor environment.
