A QoS Negotiation Framework for Heterogeneous Wireless Networks

This paper proposes a user-centric end-to-end QoS negotiation framework for heterogeneous wireless networks. The three key features of the framework are: the coordination between intra-domain QoS Broker (QoSB) and common radio resource management (CRRM) module, the QoS negotiation between QoSBs of source and destination radio access networks (RANs), and user-centric bandwidth allocation to achieve maximum user satisfaction with respect to cost. A QoS signaling procedure for the proposed QoS negotiation framework is presented. The delay associated with the signaling procedure is analyzed. It is found that the signaling procedure has no negative effect on network QoS performance.
