Reliable Distributed Computing for Metaverse: A Hierarchical Game-Theoretic Approach

The metaverse is regarded as a new wave of technological transformation that provides virtual space for people to interact through digital avatars. To achieve immersive user experiences in the metaverse, real-time rendering key technology. However, computing intensive tasks from service providers cannot be processed efficiently on single resource-limited mobile device. Alternatively, such devices can offload other by adopting collaborative paradigm based Coded Distributed Computing (CDC). Therefore, this paper introduces hierarchical game-theoretic CDC framework services, especially vehicular metaverse. In framework, idle resources vehicles, acting workers, are aggregated handle computation Specifically, upper layer, miner coalition formation game formulated reputation metric select reliable workers. guarantee management values, values calculated subjective logical model maintained blockchain database. lower Stackelberg incentive mechanism considered attract workers selected layer participate tasks. simulation results illustrate proposed resistant malicious Compared with baseline schemes, scheme improve utility provider and average profit
