User-Oriented Network Selection in Heterogeneous Integrated Networks

End-users are anticipated to have more freedom in dynamically connecting to any service provider for any service through their multi-mode terminals in the next generation heterogeneous integrated networks. This paper proposes a novel analytical framework of such a mechanism, which allows a user to freely determine one of the selection criteria, and to freely select one of the accessible networks to connect with according to his willingness. For this purpose we define the user-centric QoS and user-centric cost, and derive their expressions. We also analyses the impact that different parameters on the user expected QoS using simulation.
