Simulation of Fusion Localization Based on a Single WiFi AP and PDR

WiFi Localization and Pedestrian Dead Reckoning(PDR) are attracting increasing attention due to its wide deployment and ubiquity on smartphones respectively. In this paper, we propose a fusion system based on Kalman Filter(KF) algorithm which combines a Single WiFi AP positioning system and PDR. Single WiFi AP positions depends on ToF calculation and AoA calculation which are breakthroughs in recent researches. PDR is variant of dead reckoning system which rely on inertial sensors on mobile phones. The fusion system makes best use of the advantages and bypass the disadvantages. Simulation results demonstrate that the performance of the fusion system outperforms the two independent systems.
