Bluetooth-based Indoor Navigation Mobile System

A novel symbolic-based indoor navigation solution for Android is presented in this paper which uses Bluetooth Beacons The goal of this paper is to present the development of a Bluetooth Beacon-based Indoor Navigation System in Android. Bluetooth Beacons emit radio frequency signals, that can be used for distance calculation. Based on the distance from the beacons, the users location is estimated. Adjacency of the Bluetooth Beacons was used to trace back the way finding to well known graph problems. Thus Disktra's shortest path algorithm was used for route planning. Two user friendly navigation interfaces were designed. Experimental results verify the applicability of the presented Indoor Navigation Application.
