With the increasing popularity of smart phones, knowing the accurate position of a user has become critical to many context-aware applications. In outdoor environments, standardized Global Positioning System (GPS) is often used. However, for indoor environments such as airports, hospitals or shopping malls GPS signals are usually unavailable or unreliable. Most of the existing indoor positioning solutions try to address this problem by utilizing existing infrastructures such as Wi-Fi access points or Bluetooth beacons.
