IoT based 2D Indoor Navigation System using BLE Beacons and Dijkstra's Algorithm

Global Positioning System (GPS) has made it very convenient for the world to move at a quick pace due to its contribution in picking up locations, velocities as well as providing time synchronization. Due to poor signal strength and increased complexity involved in detailing, it is inefficient for indoor navigation over outdoor navigation. Bluetooth Low Energy (BLE) beacons-based positioning systems are used for Indoor mapping instead. The proposed system intends on establishing a 2D indoor navigation system by locating a user's position, acquiring the details of the destination of choice and calculating a path for navigation. This is achieved using a designed Indoor Positioning System (IPS) and Dijkstra's algorithm. The model also uses Internet of Things (IoT) edge technology to enhance performance and provide a platform for further analysis. An academic block of our university is considered as the testbed for the system and the obtained experimental results are discussed.
