Enhancing the Accuracy of Indoor Positioning by Using Multiple Bluetooth Low Energy Beacon Devices
Abstract— In recent years indoor positioning techniques based on the received signal strength indicator (RSSI) signal of Bluetooth Low Energy beacon devices (BLE) has become an interesting research topic. However, this beacon device has many problems in terms of positioning accuracy. RSSI emitted from these devices is not stable and the mathematical model of the current system does not produce highly accurate results. To enhance positioning accuracy, we propose to use multiple beacon devices at the same corner and filter out the RSSI deviation, which can reduce the probability of unstable RSSI. We also propose a mathematical model to calculate the exact location of the user in the system. The obtained results show that our method significantly improved the correct estimation rate of the positioning method.
