A users' satisfaction driven scheduling strategy for wireless multimedia QoS

In this work, we exploit game-theoretical concepts to depict the behaviour of multimedia users for the Radio Resource Management. Moreover, we also include pragmatic economic considerations, which allow studies of provider's revenue and possible charging mechanisms. These concepts are in particular applied to HSDPA scheduling procedures, whose main aim is to improve the performance of 3G networks and to allow extensions to a plethora of services. We briefly discuss a model for the users' satisfaction that includes both perceived QoS and pricing, already proposed to determine the QoS provisioning and network dimensioning. We apply the users' satisfaction function of this model in the scheduler. In this way we achieve improvements of the QoS as it is seen from the users' point-of-view, i.e., by involving the satisfaction of service constraints but also paid price. This analysis will be extended also to the provider's side, with considerations on the achievable revenue, that is an important aspect to take into account in service supplying.
