A Novel Procedure for Coupling QoS Control and Handover Decision for Mobility Management

Providing QoS for nomadic hosts remains a critical issue since new emerging wireless technologies may present different behaviours in terms of QoS, security or cost. Within this heterogeneous environment, especially if a handover occurs, keeping the same QoS level for one application may require some methods to negotiate the QoS provided in each network. In this paper, we propose to adopt a proactive and dynamic negotiation approach coupled with the handover decision algorithm implemented. This method is compared to two existing solutions developed in the Daidalos IST project and in the Ambient Network IST project.
