Cover Story: The aim of this study is to compensate the user’s body shadowing effect on the received signal strength indicator to improve fingerprinting-based indoor localization performance with a chest-mounted wearable device. The online phase performs additional tasks compared to the conventional fingerprinting methods to mitigate user’s BSE. Firstly, it estimates the angle between a wearable device and the reference nodes considering the user’s orientation. The idea of landmark graph along with arctangent function is used for angle estimation. To detect a landmark, an IMU-aided decision tree-based motion mode classifier is implemented. Then, a BSE compensation model is used to correct the RSSIs of the query fingerprint. Finally, the k-nearest neighbor algorithm is employed to calculate the location of an unknown target.
