  Metaverse applications that incorporate Mobile Augmented Reality (MAR)
provide mixed and immersive experiences by amalgamating the virtual with the
physical world. Notably, due to their multi-modality such applications are
demanding in terms of energy consumption, computing and caching resources to
efficiently support foreground interactions of participating users and rich
background content. In this paper, the metaverse service is decomposed and
anchored at suitable edge caching/computing nodes in 5G and beyond networks to
enable efficient processing of background metaverse region models embedded with
target AROs. To achieve that, a joint optimization problem is proposed, which
explicitly considers the user physical mobility, service decomposition, and the
balance between service delay, user perception quality and power consumption. A
wide set of numerical investigations reveal that, the proposed scheme could
provide optimal decision making and outperform other nominal baseline schemes
which are oblivious of user mobility as well as do not consider service
decomposition.
