Evaluation of a Hybrid Wi-Fi Indoor Positioning System Using Received Signal Strength Indicator (RSSI) and Trilateration Between IoT Devices

Abstract

The present research addressed a GPS problem, which is to find an indoor positioning through wireless networks. Various techniques such as path loss, trilateration, RSSI, linear regression and smoothing filters were used. Finally, a hybrid system capable of obtaining the position of an object based on the positions of sensors being used was achieved.
