Computation offloading and pricing in mobile edge computing based on Stackelberg game

Aiming at the problem of offloading optimization of transmission power and edge cloud pricing in mobile edge computing systems, this paper proposes an Offloading Strategy-and Price Control(OSPC) algorithm based on Stackelberg game. First, the Stackelberg game is used to establish the edge cloud pricing and transmission power decision model, which realizes the optimization of the utility of edge cloud and each user under the task delay constraint and the edge cloud capacity constraint; Then, a relationship model between the optimal transmission power and the amount of offloading data is established, which simplifies the user's optimal transmission power offloading decision; Finally, an OSPC algorithm is studied, which achieves the optimal pricing of edge cloud utility maximization and the optimal offloading strategy for each user to maximize their own utility under this pricing. The simulation results show that the method proposed in this paper not only guarantees the utility of the edge cloud, but also maximizes the utility of users, and the algorithm has good convergence and scalability.
