A Hybrid Indoor Positioning System Design based on BLE
Journal Title: Invention Journal of Research Technology in Engineering & Management - Year 2018, Vol 2, Issue 10
Abstract
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. BLE (Bluetooth Low Energy) technology has developed for location services during the last few years, the Beacons using BLE technologies are transmitter devices that 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 method is also applied to improve the accuracy and stability of indoor position. Some popular machine learning algorithms are evaluated as the training model of positioning prediction. The hybrid 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.
