Abstract
Location-based services (LBS) in indoor location are for providing information needed by users, and this information can be provided to users based on a geofence. The most important component of location-based service systems is GPS, which does not have the ability to determine the location in indoor location. In this research, LBS Android software was developed for museums with the possibility of providing multimedia information based on the Geofence concept. The visitor is first positioned by IPS in this software, and multimedia information is presented to the visitor by being placed in the Geofence. To determine the user’s location, BLE-based transmitters were installed, and the Trilateration algorithm was used to develop a two-dimensional positioning system in indoor location. The main input variables of this algorithm were the distance of the transmitters from the user and the X and Y coordinates related to the installation location of the transmitters. RSSI was used to obtain the distance between the visitor and the transmitters, and the coordinates of the transmitters were measured in terms of X and Y dimensions relative to the reference point. The positioning accuracy of the system was evaluated based on RMS and apparent error in the environment. The final apparent error is equal to 1.02975 and the apparent error range is (0.43-1.44) meters.
