Abstract
The Metaverse is a virtual environment where users are represented by
avatars to navigate a virtual world, which has strong links with the
physical one. State-of-the-art Metaverse architectures rely on a
cloud-based approach for avatar physics emulation and graphics rendering
computation. Such centralized design is unfavorable as it suffers from
several drawbacks caused by the long latency required for cloud access,
such as low quality visualization. To solve this issue, in this paper,
we propose a Fog-Edge hybrid computing architecture for Metaverse
applications that leverage an edge-enabled distributed computing
paradigm, which makes use of edge devices computing power to fulfil the
required computational cost for heavy tasks such as collision detection
in virtual universe and computation of 3D physics in virtual simulation.
The computational cost related to an entity in the Metaverse such as
collision detection or physics emulation are performed at the end-device
of the associated physical entity. To prove the effectiveness of the
proposed architecture, we simulate a distributed social metaverse
application. Simulation results shows that the proposed architecture can
reduce the latency by 50\% when compared with the legacy
cloud-based Metaverse applications.
