Mobile Edge Computing for 6G Non-Terrestrial Networks: A Survey

초록

In order to provide high-speed, low-latency connectivity, 6G technology emerges as a promising solution, offering terahertz-frequency operation, ultra-low latency, and seamless integration with cutting-edge technologies like artificial intelligence, quantum computing and blockchain. In order to extend connectivity to remote regions, the integration of non-terrestrial networks (NTNs), including satellites and unmanned aerial vehicles (UAVs), with 6G networks has become imperative. Moreover, the integration of mobile edge computing (MEC) into 6G terrestrial networks (TNs) and NTNs plays a crucial role in minimizing latency, optimizing backhaul traffic, and enhancing user experience by bringing computational resources closer to end-users. To this end, this paper presents various deployment scenarios for MEC servers, including base stations, UAVs, satellites, and gateways, and explores different user access scenarios for both TNs and NTNs. By providing a comprehensive overview of 6G TNs and NTNs, and their integration with MEC, this paper addresses existing research, tackles challenges, and outlines future directions to propel wireless communication and computing paradigms forward.
