Outline of Final Research Achievements

This research aims to develop an indoor localization without newly deployed reference nodes by utilizing WiFi APs as reference nodes. Literature reported many indoor sensor localization systems, which require reference nodes. When we localizate huge number of sensors, we face reference deployment problem. We therefore developed a sensor localization system that uses WiFi APs installed in the environment as reference nodes. Sensor nodes are equipped with ZigBee (IEEE 802.15.4) modules that cannot demodulate WiFi (IEEE 802.11) signals. We therefore developed a cross-technology signal detection method that detects periodic beacon signals sent from WiFi APs.
