Two-stage Stackelberg game based physical reality sensing incentive mechanism in metaverse

Abstract

With the development of digital twin technology, the concept of the metaverse has come into the limelight. How to motivate mobile users to collect physical reality sensing data to build the metaverse has become the focus of research. In this paper, a physical reality incentive mechanism is proposed based on two-stage Stackelberg game. Considering the competitive relationship between mobile users, a multi-leader multi-follower Stackelberg game model is constructed to describe the interaction between mobile users and virtual service providers (VSPs). In order to maximize the utilities of mobile users and VSPs, a unique Stackelberg equilibrium solution is derived to obtain the optimal incentive strategy. Simulation results show that our proposed incentive method is effective in motivating mobile users to participate in the physical reality sensing tasks. The overall social welfare can be increased in the metaverse physical reality sensing networks.
