摘要

The integration of LoRaWAN technology with satellite networks presents a transformative solution for environmental monitoring in remote flood-prone regions, addressing critical gaps in current disaster prevention infrastructure. This paper provides a comprehensive technical analysis of hybrid terrestrial-satellite LoRa systems, systematically examining three fundamental challenges that require detailed consideration. Through extensive MATLAB and Castalia simulations, combined with rigorous mathematical modeling, we demonstrate that LoRa modulation maintains exceptional robustness with packet delivery ratios exceeding 0.88 under Doppler shifts up to 50 Hz when properly configured with optimized spreading factors between SF11 and SF12. Our novel adaptive MAC protocol architecture shows significant improvements over standard LoRaWAN implementations, achieving 34–39% reduction in energy consumption while simultaneously improving packet delivery ratios by 15–38% across various node densities.
