Edge Computing-enabled Network Architecture Design for Space-Air-Ground Integrated Network

The space-air-ground integrated network (SAGIN) has become important research content for the next generation of 6G communication networks. Considering the difficulties in network resource management, complex network service configuration, network collaboration and security sharing pressure in network construction. A novel edge computing-enabled network architecture is proposed. On this basis, key technologies such as software defined network (SDN), network slicing and blockchain are used to solve the difficulties in network system construction. Then, the proposed architecture is designed and described in detail. Furthermore, the key technical challenges in the practical application and implementation of the proposed architecture are further explored, providing a fundamental reference for further in-depth research. Finally, simulation experiments verify that the proposed architecture achieves significant improvements in terminal devices' task processing energy consumption and latency compared to network architecture with other studies.
