Guest Editorial: Introduction to the Special Section on Intelligence-Empowered Collaboration Among Space, Air, Ground, and Sea Mobile Networks Towards B5G

The papers in this special section focus on intelligence-empowered collaboration among air, space, ground, and sea mobile networks. Providing ubiquitous network accessibility is one of the most essential goals in the Beyond 5G (B5G) mobile networks. To achieve this goal, it is vital to integrate the space, air, ground, and sea networks (SAGS) to form such heterogenous B5G networks. Although the above networks exhibit different types of technical issues, they should be connected seamlessly with collaborated networking functionalities and management. Besides, recently, the application and innovation of artificial intelligence (AI) have also been attracting significant research attentions to enable intelligent networking and communication, where the network quality can be ensured by meeting the key performance metrics. However, it remains unclear if there is a fundamental science and engineering paradigm that can integrate networking with heterogeneous communication network applications efficiently and effectively on a large scale.
