In the latest edition of IEEE Transactions on Wireless Communications, researchers Jiajie Xu, Mustafa A. Kishk, and Mohamed-Slim Alouini unveil a pioneering approach to enhance global connectivity in challenging terrains. Their paper, titled "Space-Air-Ground-Sea Integrated Networks: Modeling and Coverage Analysis," explores Space-Air-Ground networks' potential in the forthcoming sixth-generation (6G) wireless communication era.
"Connectivity in remote maritime areas has been a longstanding challenge. Our research offers a promising solution by introducing Space-Air-Ground-Sea Integrated Networks (SAGSINs). Our research explores the untapped potential of SAGSINs in enabling seamless global connectivity. By extending our networks to the ocean surface, we're paving the way for a new era of communication," says Jiajie Xu, a PhD Candidate at KAUST and first author of the study.
Motivated by the need for connectivity in remote maritime locations, the study introduces Space-Air-Ground-Sea Integrated Networks (SAGSINs). "SAGSINs represent a novel framework that redefines how we approach wireless communication in challenging environments," notes Mustafa A. Kishk, co-author who contributed as a postdoctoral researcher at KAUST and now serves as an assistant professor at Maynooth University in Ireland.
Practical scenarios and channel modeling techniques are employed. Jiajie Xu adds, "Our findings demonstrate that as surface stations (SSs) move away from the coastline, different relay stations provide varying signal strengths, ultimately enabling reliable communication in even the most remote oceanic locations."
This research has far-reaching implications for maritime communication and wireless connectivity in challenging environments. "It underscores SAGSINs' potential to shape the future of wireless networks," concludes Mohamed-Slim Alouini, Al-Khawarizmi Distinguished Professor of Electrical and Computer Engineering at KAUST.
