Human-Centric Resource Allocation for the Metaverse With Multiaccess Edge Computing
This addresses resource allocation challenges for users in the metaverse using multi-access edge computing, representing an incremental improvement over existing methods.
The paper tackles the problem of optimally allocating limited communication and computation resources at the edge for the metaverse, proposing an adaptive method based on multi-agent soft actor-critic with graph convolutional networks (SAC-GCN), which improves overall user experience, balance of resource allocation, and resource utilization rate by at least 27%, 11%, and 8%, respectively.
Multi-access edge computing (MEC) is a promising solution to the computation-intensive, low-latency rendering tasks of the metaverse. However, how to optimally allocate limited communication and computation resources at the edge to a large number of users in the metaverse is quite challenging. In this paper, we propose an adaptive edge resource allocation method based on multi-agent soft actor-critic with graph convolutional networks (SAC-GCN). Specifically, SAC-GCN models the multi-user metaverse environment as a graph where each agent is denoted by a node. Each agent learns the interplay between agents by graph convolutional networks with self-attention mechanism to further determine the resource usage for one user in the metaverse. The effectiveness of SAC-GCN is demonstrated through the analysis of user experience, balance of resource allocation, and resource utilization rate by taking a virtual city park metaverse as an example. Experimental results indicate that SAC-GCN outperforms other resource allocation methods in improving overall user experience, balancing resource allocation, and increasing resource utilization rate by at least 27%, 11%, and 8%, respectively.
