WiFi positioning system without AP locations for indoor evacuation guidance

摘要

This research considers an application for a smartphone to support indoor evacuation guidance used in a building which contains many laboratories at a university, and proposes a simple WiFi positioning system without AP locations. The proposed system can recognize user's location by using a hierarchical neural network and the input of the network is only a list of detected SSIDs by a smartphone. The system is implemented on the smartphone and evaluated the recognition rate.
