The BDD navigation tracking systems using the beacon

초록

There are many guidance systems for people using tracking systems where in railway, airports, trade fairs, shopping centers, office, tourism, and industry. The beacon with Bluetooth Low Energy is a wireless personal area network technology and can be used many applications to calculate the exact location. However, from an accuracy perspective, a big problem with this approach is the Received Signal Strength Indication (RSSI) of weak signal caused by having an obstacle between the BLE modules such as beacons, smartphone, tablet PC. This paper proposes a Beacon Detection and Direction (BDD) algorithm that can track and guide in indoor position more advanced than previous server-based or client-based application. It not depend on only RSSI because of the big problem which is weak signal by hindrance. To calculate accuracy position, the proposed algorithm is combined a server-based approach and a client-based application. It has three tables and beacons that are divided three types are deployed inside location at regular intervals. Using the proposed algorithm we try to test the navigation tracking and the results show that BDD provides an accurate and effective route.
