The sensor data collection satellite (SDCS) system, as a part of the Internet of Things (IoT), enables data transmission in areas without Internet and mobile communication coverage. A novel technology named LoRa for Low power wide area network (LPWAN) enables energy-efficient communication over long distances, which can meet the requirement of energy-constraint in SDCS system. However, the LoRaWAN as the MAC protocol of LoRa has the problem of initial channel allocation and power selection if directly used in SDCS system. In this paper, we propose a SA-LoRaWAN protocol for power adaptation based on position information of sensors and satellite, and sensors can dynamically access channel according to the packet buffer size. We use OPNET to model SDCS system based on SA-LoRaWAN protocol, and the simulation results demonstrate that the proposed protocol can reduce the energy consumption and improve the packet delivery rate.
