In this paper, the authors describe an Android application for indoor map guidance system that guides visitors inside the public buildings (colleges, schools, shopping malls etc). It utilizes Bluetooth technology which is at lowest cost. They propose a new approach that uses Bluetooth module to determine the location of person inside the building. So for this they are using routing algorithm (Dijkstra's algorithm) to find the shortest path from user's location to destination. By using Bluetooth, sufficient accuracy can be achieved in indoor navigation. They are using Bluetooth technology because GPS does not provide sufficient range inside buildings.
