Abstract

Increased development in the area of networking has coincided with an increased demand for multimedia services via high data rates. Nevertheless, adaptation of the current volume of multimedia data to capacity-limited commercial wireless networks has not kept pace. The Wireless Broadband (WiBro)/Mobile Worldwide Interoperability for Microwave Access (WiMAX) system, which is expected to be one of the platforms for 4G wireless communications, entertains several kinds of service classes with respect to the characteristics of services. However, no effective techniques have been specified to deal with the quality degradation that occurs in conjunction with either dynamic channel fluctuation or throughput dropping at the cell edge over highly error-prone channel environments. In this paper, we define a new service class, advanced real-time Polling Service (artPS), that adapts to the channel variation by introducing layered coding like Scalable Video Coding. Utilizing this artPS class, the proposed system very efficiently achieves higher Quality of Service, while maintaining backward compatibility with the conventional system and attaining the multiplexing gain of layered data.
