WiFi; RSS; indoor positioning;

Indoor location-based services have high requirements for positioning accuracy. Fingerprint positioning methods are popular, where Received Signal Strength (RSS) of WiFi is widely used because of its availability. Our dataset is from the dataset provided in the literature [1]. The WiFi measurements were collected in an area among the bookshelves in a wing of a university’s library building. The collection process was finished with a Samsung Galaxy S3 smartphone and software explicitly developed, and a total of 448 Access Points (APs) were detected during the experiment.
