An Enhanced RSSI-based Framework for Localization of Bluetooth Devices

With the rapid development of Bluetooth technology, Bluetooth modules have begun to be widely used in many devices. Although a large amount of the research and applications have been developed in tracking the locations of Bluetooth devices, the accuracy of the position of a targeted Bluetooth device has been severely impacted by various factors, such as the obstacles between communication, signal noise raised by other sources, and various algorithms used by the applications. In this project, based on a thorough survey of the current research and development in Bluetooth positioning, an enhanced framework constructed with Received Signal Strength Indicator (RSSI), was proposed. Aiming a practical evaluation on how the newly proposed framework improves the accuracy of the location of a targeted Bluetooth device, a prototype system was carefully designed and physically implemented. As the data obtained from the experiments performed on the prototype system indicates, this enhanced RSSI-based framework, PanoBLE, possesses its unique promising characteristics over existing systems and frameworks in positioning Bluetooth devices.
