Performance Evaluation of Dynamic Transmission Parameter Control Method for Mobile Terminal with 920 MHz LoRa Communication

Low Power Wide Area (LPWA) is expected to be a communication technology suitable for the Internet of Things (IoT) due to its features, such as low power consumption, low cost, and long-distance transmission. Since LoRa communication has a trade-off between communication range and transmission rate, its communication performance is inherently varied depending on the surrounding environment. Therefore, in the previous study, we proposed a dynamic parameter control method based on beacon reception characteristics to fixed nodes to provide stable and efficient communication and evaluated its effectiveness. However, since the communication environment for mobile nodes is constantly changing, that method is challenging to contribute to performance improvement for mobile nodes. This paper proposes a dynamic transmission parameter control method for mobile terminal with LoRa communication. The effectiveness of the proposed method is evaluated from the real experiments.
