Call Admission Control for Integrated Multimedia Service in Heterogeneous Mobile Hotspots
Mobile hotspots are a promising trend to offer ubiquitous multimedia services even in public transit vehicles such as buses, trains, and airplanes. However, it is very challenging due to high mobility, fast channel fading, and stringent multimedia Quality-of-Service (QoS) constraints. Effective admission control is necessary to limit the admitted traffic so that accepted users are provided QoS guarantee. In this paper, the authors develop a comprehensive analytical framework for the performance of interactive data service and conversational video service in mobile hotspots with heterogeneous wireless technologies.
