“…These results are very similar or even slightly better than the results reported in the former papers [13,16,17,18,19]. Our approach has the advantage of not depending on offline training data, which enables it to automatically constructed the positioning system and dynamically model the changes in the environment.…”

“…Nevertheless, this simple idea produces inaccurate radio maps, which decrease the accuracy of the location estimation. Consequently, many other attempts have been proposed, including the free-calibration methods [13,14,15,16,17,18,19,20], user-aided methods [21,22] and the auto-update technologies [23]. …”

“…The conventional way of creating fingerprint training data-base is to periodically conduct extensive drive test campaigns which are time-consuming and unpractical for building a metropolitan-scale radio map of the locating system [41], [12]. A major drawback of this method is to update the training radio map when new APs are deployed and existing APs are decommissioned.…”

“…The establishment of fingerprint space determines the positioning range and positioning accuracy of Location Fingerprinting. Since the interpolation can reduce the number of sampling points, improve the efficiency of fingerprint space building and ensure the positioning accuracy, it becomes one of the research focuses on extending positioning range [3] [4] . The major existing interpolation method to establish fingerprint space is the traditional Kriging [5] , log-propagation path loss model [6] [7] and the weighted distance inverse IDW [8] .The former two methods do not consider the relationship of sampling points, ignore the influences of the entire fingerprint spatial sampling points towards the measuring point correlation, resulting in lower interpolation accuracy.…”
