Abstract

Recently, location-based services have become very popular. Ubiquitous
positioning is elementary for the the Internet of Things. Hence,
obtaining precise location information is a core feature of recent
wireless sensor networks (WSNs). Besides of location-awareness,
energy-efficiency is another essential property of a modern sensor
network. RSSI-based direction finding is a prospective approach for WSNs
providing low-power positioning. However, radio-based localization
techniques, including RSSI-based direction finding, are prone to fading
effects of the wireless propagation channel. Therefore, a-priori
knowledge of channel parameters is inevitable for precise positioning.
Fading parameters rapidly change when traversing different environments.
Thus, a-priori channel knowledge can not be expected. In this paper, we
apply adaptive Kalman Filters to the problem of simultaneous estimation
of position and channel parameters. Applicability is proven by
simulations and a field trial tracking bats in a forest.
