An Efficient and Certified LEO Satellite-Enabled Smart Management System

Low Earth orbit (LEO) satellite systems are gaining popularity in the development of next-generation communication networks due to their ability to deliver broad and efficient communication services in remote and isolated areas where deploying base stations is not cost-effective. In this work, we present the design of a satellite-enabled system for efficient and certified service providing. First, taking advantage of the LEO satellite communications, our system can support a large number of various types of sensors including wind speed sensors, temperature sensors, cameras, etc. operating simultaneously and acquiring their information in real time. Second, to enhance the long-term maintenance of communication services and the collaboration of each device, a federated spectrum learning method for dynamic spectrum access is proposed. Third, blockchain technology is utilized in the global model aggregation in federated learning to strengthen the decentralization of the architecture for security purposes. We also present the details of each component of the designed system to demonstrate its feasibility and effectiveness.
