As the field of the application of the Internet of Things (IoT) expands, Low Power Wide Area Network (LPWAN) technologies are attracting attention. Among them, the research on Long Range (LoRa) that enables low energy consumption and long distance communication in the ISM band is actively being conducted. The frame loss and collision occur during the frame transmission in the LoRa network and the Adaptive Data Rate (ADR) mechanism is used in the LoRaWAN to resolve this problem. The ADR mechanism is a method of allocating transmission parameters to each node in consideration of the network conditions. However, the existing ADR mechanism has limitations in terms of energy consumption and frame delivery rate in the specific environments. In this paper, we propose an ADR mechanism to properly distribute transmission parameters in consideration of the energy consumption and frame delivery rate. In various simulation environments, the experiments of the proposed ADR mechanism are conducted. Through these experiments, it shows the performance and characteristics of the proposed mechanism in terms of frame delivery rate and energy efficiency. |
