  The Metaverse has emerged as the next generation of the Internet. It aims to
provide an immersive, persistent virtual space where people can live, learn,
work and interact with each other. However, the existing technology is
inadequate to guarantee high visual quality and ultra-low latency service for
the Metaverse players. Mobile Edge Computing (MEC) is a paradigm where proximal
edge servers are utilized to perform computation-intensive and
latency-sensitive tasks like image processing and video analysis. In MEC, the
large amount of data is processed by edge servers closest to where it is
captured, thus significantly reducing the latency and providing almost
real-time performance. In this paper, we integrate fundamental elements (5G and
6G wireless communications, Blockchain, digital twin and artificial
intelligence) into the MEC framework to facilitate the Metaverse. We also
elaborate on the research problems and applications in the MEC-enabled
Metaverse. Finally, we provide a case study to establish a thorough knowledge
of the user utility maximization problem in a real-world scenario and gain some
insights about trends in potential research directions.
