With the growth of bandwidth adaptive applications in wireless and mobile networks with different QoS requirements, there is an urgent need for an adaptive bandwidth management scheme which makes use of the flexible bandwidth requirements of these new traffic classes. In this paper, a Call Admission Control (CAC) strategy is proposed based on full consideration of the adaptivity of multimedia services...
Provisioning of guaranteed Quality of Service (QoS) in next generation cellular networks has become a great challenge specially, when the wireless access networks have been used to deliver the multimedia services. Call Admission Control (CAC) is one of the most important components of Radio Resource Management (RRM) that affects the provided bandwidth utilization efficiency and QoS guarantees. In...
With the rapid development of wireless communications, various wireless networks will coexist. UMTS and WLAN, a popular and representative interworking paradigm, provides a plethora of multimedia services to mobile users with multimode access capability. In this paper, we propose an effective call admission control (CAC) scheme which is based on bandwidth reservation scheme. In addition, we propose...
