Dubbed "the successor to the mobile Internet", the concept of the Metaverse
has grown in popularity. While there exist lite versions of the Metaverse
today, they are still far from realizing the full vision of an immersive,
embodied, and interoperable Metaverse. Without addressing the issues of
implementation from the communication and networking, as well as computation
perspectives, the Metaverse is difficult to succeed the Internet, especially in
terms of its accessibility to billions of users today. In this survey, we focus
on the edge-enabled Metaverse to realize its ultimate vision. We first provide
readers with a succinct tutorial of the Metaverse, an introduction to the
architecture, as well as current developments. To enable ubiquitous, seamless,
and embodied access to the Metaverse, we discuss the communication and
networking challenges and survey cutting-edge solutions and concepts that
leverage next-generation communication systems for users to immerse as and
interact with embodied avatars in the Metaverse. Moreover, given the high
computation costs required, e.g., to render 3D virtual worlds and run
data-hungry artificial intelligence-driven avatars, we discuss the computation
challenges and cloud-edge-end computation framework-driven solutions to realize
the Metaverse on resource-constrained edge devices. Next, we explore how
blockchain technologies can aid in the interoperable development of the
Metaverse, not just in terms of empowering the economic circulation of virtual
user-generated content but also to manage physical edge resources in a
decentralized, transparent, and immutable manner. Finally, we discuss the
future research directions towards realizing the true vision of the
edge-enabled Metaverse.
