A Bluetooth Location Method Based on kNN Algorithm

The Bluetooth sensor networks provides us with a very feasible solution for obtaining indoor locations. We can use the Bluetooth sensor to obtain the indoor position by establishing fingerprint database. In the process of positioning by fingerprint database, the matching positioning method is an important research directions of fingerprint database positioning technology. In this work, we proposed a kNN algorithm based Bluetooth fingerprint library location method. The kNN algorithm processes the matching of measured RSSI value and the closest value in the fingerprint library. Experiment result show that it is very simple and intuitive to obtain the positioning position.
