Resource Perception Technology in the Space-Ground Fusion Network

The space-ground fusion network is an significant network architecture for overcome the limitations of ground networks in the future, achieving seamless coverage and ubiquitous connection of multiple spaces such as air, space, ground and ocean. However, its natural network heterogeneity makes efficient use of limited resources between subnets become a technical challenge. Therefore, how to accurately perceive resources in the integrated information network of Ground-Air-Space, ensure end-to-end QoS for users, and improve overall network performance is an important challenge faced by the integrated network of Ground-Air-Space. The paper introduce the resource perception both domestically and internationally, which laying the foundation for future research.
