Dynamic multimedia pricing scheme based on three-party Stackelberg game in Internet of vehicles
The user quality of experience(QoE)is reduced due to the low enthusiasm of the relay vehicle data forwarding and the limited storage space in the current Internet of vehicles(IoV)application scenarios.Thus,a dynamic multimedia pricing scheme based on the three-party Stackelberg game was proposed.Aiming at incentivizing relay vehicles to participate in forwarding multimedia content,a new multimedia content pricing framework was proposed,in which the relay vehicle received a full commission and then paid a partial commission to the roadside unit(RSU).A dynamic pricing model based on Stackelberg game was designed to establish a utility function,which was based on the storage space utilization,the content data size and the cost of the relay vehicle,the user vehicle and the RSU.The utility function was transformed into a three-party,four-stage Stackelberg pricing model.The existence of the Nash equilibrium solution was proved using backward induction technique,and the dynamic pricing process among the three parties was finally realized to achieve their respective optimal strategies.The simulation results showed that the proposed scheme effectively solved the problem of overloaded storage space in the relay vehicle and improved the enthusiasm of the relay vehicle,and it had advantages over the traditional scheme in improving user QoE.
