Stackelberg-game based pricing framework for hybrid access control in femtocell network

In this study, we propose a novel dynamic hybrid access algorithm for single femtocell network with two different types of users, the femtocell registered users (FRUs) and unregistered users (FURUs). Considering the selfish nature of the femtocell, how to provide enough incentives to the femtocell base station (FBS) for sharing its resources with the FURUs is challenging. Different from the previous works in this area, we adopt the Stackelberg-game modeling to represent the competition behaviors of the FBS and the users. Specifically, the proposed framework has the FBS to allocate resources to the FURUs through pricing while maintaining the quality of service (QoS) of the FRUs, which is done via the optimal solutions of the maximization of the utility functions of the buyers and the revenue of the seller. Simulation results show that upon the QoS of the FRUs are protected, the FBS dynamically determines the list of the accessible FURUs according to the assigned gain to the FURUs and the change of the FRUs´ QoS demands.
