Abstract

Future communication systems are expected to provide a broad range of multimedia services with guaranteed Quality of Service (QoS). Therefore, effective management of the limited radio resources is important to enhance the network performance. In this paper, we propose a QoS adaptive multimedia service framework for controlling the traffic in Multimedia Wireless Networks (MWN) that enhances the current methods used in cellular environments. The proposed framework is designed to take advantage of the Adaptive Bandwidth Allocation (ABA) algorithm with new calls in order to enhance the system utilization and blocking probability of new calls. The performance of our framework is compared to a framework previously proposed in [4]. Simulation results show that our QoS adaptive multimedia service framework outperforms the previous framework in terms of new call blocking probability, handoff call dropping probability, and bandwidth utilization.
