It is known that it is necessary to build a “high-quality” DB constructed using various data in the BLE positioning system using fingerprint. However, the “cost” of this construction such as preparation of multiple devices, data collection time, processing of constructing DB, and so on is so high. Therefore, we evaluate a method to reduce the number of data used for the DB without degrading the positioning performance in positioning phase to collate the DB with the measurement. As a result of the evaluation, even if the number of data used for the DB is decreased, by using the cooperative algorithm proposed by the authors, the result that the positioning performance can be kept equal to or higher than that of the previous method (Scene Analysis) is shown.
