A hybrid indoor-position mechanism based on bluetooth and WiFi communications for smart mobile devices

With the development of embedded systems and the advance of communication network technologies, the positioning and creative value-added applications have been used widely. The global positioning system (GPS) cannot satisfy the requirements of indoor position applications. The GPS signals cannot be received in the indoor environment. Although the Wi-Fi position technologies are used for indoor location applications, the position accuracy is not accepted. Thus, this paper proposes a hybrid indoor-position mechanism based on Bluetooth and Wi-Fi communications. In the experiments, the position performance of using Wi-Fi and Bluetooth wireless signals with Neighboring Weighted Positioning method is better than that of using only Wi-Fi wireless signals. The average deviation of less than 5 meters and standard deviation of less than 2 meters.
