Indoor Positioning Using Combination of Wi-Fi Fingerprint and Inertial Positioning

Indoor positioning via mobile device is one of the unexploited research area. With the popularity of Wi-Fiaccess points inside buildings, Wi-Fi localization becomes one of the feasible method to assist the indoor positioning. However, due to the complication of indoor environment, indoor positioning merely depending on Wi-Filocalization is not robust against interference of electromagnetism and structure of the building. Thus, with the assistance of inertial positioning technique, we present a robust indoor positioning technique and it gains good performance on energy consumption and localization accuracy.
