| In recent years, positioning services are increasingly used for
navigation with the growing popularity of smart devices. The
indoor positioning is a much tougher challenge than outdoor
positioning. The Beacons using BLE (Bluetooth Low Energy)
technologies are transmitter devices that broadcast signals.
These devices can take advantage of Received Signal
Strength Indication (RSSI) information together with an
appropriate localization algorithm, to pinpoint a user’s
position. We apply the Triangulation algorithm to compute the
user’s position based on the RSSI of iBeacon devices, and the
Fingerprinting is also applied to improve the accuracy of indoor
position. The positioning system constructed with client-server
architecture for reducing the computation of mobile devices,
which makes indoor positioning application more stable and
provides other diversified services.
