Stackelberg Game-Theoretic Spectrum Allocation for QoE-Centric Wireless Multimedia Communications
Multimedia Quality of Experience (QoE) is a predominant factor that drives customer satisfaction and user experience in the future wireless networks. This paper proposes a Stackelberg game theoretic spectrum allocation approach for QoE-centric wireless multimedia communication rather than the traditional data traffic. Here, we introduce the cost of utilizing the spectrum as a factor in the utility of the service provider and the client device. Both service provider and client devices are assumed rational and selfishly look to maximize their utility in a non-cooperative manner. Stackelberg game is used to formulate the interaction between the service provider and the client device, and to derive the Nash Equilibrium for the utility maximization problem. The paper proves existence of a Stackelberg game solution such that the utility of both client device and the service provider is maximized. The simulation results demonstrate that QoE and fairness can be achieved by the proposed game-theoretic spectrum allocation scheme.
