Abstract
Navigation is the process of the user positioning and redirecting to their desired destination. Nowadays, people majority use Global Positioning System (GPS) for outdoor navigation process. However, the lack of GPS signal reception inside the buildings makes indoor navigation process an interesting challenge. In this paper, a new indoor navigation system based on Bluetooth Low Energy (BLE) is proposed. Moreover, a more efficient routing technique based on A* algorithm is utilized. Finally, a local web application for navigation through the third floor, building 8, Faculty of Engineering, Cairo University is demonstrated.
