A Survey on Resource Management in Joint Communication and Computing-Embedded SAGIN
arxiv(2024)
摘要
The advent of the 6G era aims for ubiquitous connectivity, with the
integration of non-terrestrial networks (NTN) offering extensive coverage and
enhanced capacity. As manufacturing advances and user demands evolve,
space-air-ground integrated networks (SAGIN) with computational capabilities
emerge as a viable solution for services requiring low latency and high
computational power. Resource management within joint communication and
computing-embedded SAGIN (JCC-SAGIN) presents greater complexity than
traditional terrestrial networks. This complexity arises from the
spatiotemporal dynamics of network topology and service demand, the
interdependency of large-scale resource variables, and intricate tradeoffs
among various performance metrics. Thus, a thorough examination of resource
management strategies in JCC-SAGIN is crucial, emphasizing the role of
non-terrestrial platforms with processing capabilities in 6G. This paper begins
by reviewing the architecture, enabling technologies, and applications in
JCC-SAGIN. Then, we offer a detailed overview of resource management modeling
and optimization methods, encompassing both traditional optimization approaches
and learning-based intelligent decision-making frameworks. Finally, we outline
the prospective research directions in JCC-SAGIN.
