Development of indoor positioning system based on Bluetooth

In today’s highly urbanized environment, indoor space is becoming more and more complex. In this paper, a fast real-time positioning system with high precision and low cost is developed based on Bluetooth signal. In this paper, the clients and servers are established with several Raspberry Pis, which can sense mobile detection targets by detecting Bluetooth signal. Information exchange is realized through web-based and embedded database applications. The smoothing algorithm is adopted to reduce positioning error, and graphical display technique is adopted for visualizing location information. The desired result is an integrated solution for Bluetooth-based indoor positioning system, which has a good application performance and practicability.
