Abstract: | The present Master Thesis describes the development of a low-cost Indoor Positioning System based on the technology Bluetooth Low Energy and state-ofthe- art positioning techniques. The system proposes a processing scheme that separates the positioning kernel from a particle filter, which enhances the location precision. The techniques used as positioning kernel are multilateration and fingerprinting based on RSSI measurements, which are filtered previously by a Kalman filter. In addition, the system provides a semantic positioning service based on a Support Vector Machine (SVM) classifier. The system has been designed as a web service, facilitating its integration, scalability, and maintainability. Testing was carried out by deploying the system with BLE beacons based on the microcontroller ESP32 as well as two Android terminals, across two different scenarios, namely: a Room (37 m2), with line-ofsight between the beacons and the terminal, and a Floor (135 m2), without line-ofsight. The yielded results demonstrate that the system prototype works with a location error of approximately 1.5 meters and an average room classification precision of 91% in domestic environments. This performance validates the design according to the project’s objectives. In conclusion, this thesis showcases how such a widely spread technology like BLE can be effectively used for indoor positioning applications with a low development cost. |
