Today, the overwhelming majority of mobile devices have the ability to connect to the Internet via wireless or cellular networks. According to recent statistics, we tend to spend 80-90% of our time indoors. These two events have exaggerated interest in discovering indoor geolocation solutions since satellite positioning (GPS) is not available in buildings. This was the motivation for the development of positioning algorithms based on the existing WLAN infrastructure and the use of fingerprint (RSS) signals. So far, the goal is to improve accuracy and the proposed methods are usually evaluated only in terms of precision in small-scale arrangements. However, the time taken to calculate the user's location is equally important, since it may violate real-time application limitations. In addition, low energy consumption is another important condition. However, both time estimation and battery exhaustion during positioning have received little attention, especially on mobile devices. In the context of this work we developed an indoor positioning application using the WLAN infrastructure of the site.
