Abstract

Abstract

There are four traffic classes in wireless multimedia network, including conversational class, streaming class, interactive class, and background class, while three of them are Variable Bit Rate (VBR) traffic except conversation class. It will fall into a dilemma if conventional resource allocation methods are adopted (especially for the bandwidth allocation methods). In this paper, a dynamic bandwidth allocation scheme is proposed for packet switched wireless multimedia networks. The scheme could guarantee users QoS, while the utility of resource could be improved. Using these models, the effects of the changeable QoS dynamic bandwidth allocation and optimization strategy are evaluated from both points of view of the networks and users. Simulation results are presented to demonstrate the performance of the proposed scheme in terms of system capacity, blocking probability, delay, practical transmission ratio of video traffic, and the Integrated Grade of Service (IGoS) of VBR traffic. Compared with the conventional scheme, the proposed scheme can greatly improve the system performance and resource utility.
