Wireless service provider selection and bandwidth resource allocation in multi-tier HCNs
Résumé
In this work, the inter-linked problems of band-width allocation by wireless service providers (WSPs) and WSP selection by users in heterogeneous cellular networks (HCNs) are addressed. This work employs a multi-hierarchical game framework. While the interaction between users are modelled using evolutionary game theory, the interactions between competing WSP's are modelled as a non-cooperative spectrum bandwidth allocation game (N-BAG). Finally the interaction between the WSPs and the users is modelled as a multi-leader multi-follower Stackelberg game. Moreover, for the formulated evolutionary game, the existence and uniqueness of the evolutionary equilibrium (EE) was investigated. Conditioned on the obtained EE, the existence of a Nash equilibrium (NE) for the proposed N-BAG was proven and an offline algorithm to achieve the equilibrium state was proposed. Finally, simulation results verify the validity of the analysis and demonstrate that a unique NE would be achieved by the HCNs adopting the proposed scheme.
