FUZIPS: Fuzzy v2 Based Algorithm for Automatic Switching from GPS Based Location Services to the Indoor Positioning Service

Abstract

We address the problem of seamless positioning/navigation and ubiquitous localization. The problem is relevant for commercial service providers who are interested that their positioning services will be able to work seamlessly in all environments, including, indoor, urban, and rural. We present an algorithm capable of automatic switching from traditional location services (GPS, A-GPS) to indoor positioning systems (WiFi based triangulation, Bluetooth LE beacons). The proposed fuzzy logic algorithm based on the signal strength and the distance showed a better result than the Proximity algorithm based only on the signal strength, reaching an error rate of 12%.
