Abstract: This paper introduced a low-cost platform for locating bluetooth cell phones and releasing position information. The authors improved the scheme of measuring Received Signal Strength Indication (RSSI) of bluetooth devices to locate multiple cell phones simultaneously, developed cell phone program to receive position information via Wi-Fi and display it on map. The experimental results show that the system is accurate in positioning and easy to use, and it provides a platform support for applications of Internet of Things (IOT) under current hardware condition.
