Implementing QoS support for wireless multicast nodes

High quality multimedia streaming over wireless networks require the use of suitable quality of service (QoS) mechanisms. Real-time multimedia streams such as radio or TV Webcasts are well suited for multicast transmission. Nonetheless, QoS for wireless multicast remains an active research area since existing QoS mechanisms and methodologies were developed primarily for carrying unicast traffic through wired networks. The research goal is to optimize overall system throughput fur supporting several competing QoS-aware multicast media streams in best-effort wireless networks. This paper describes new QoS adaptation mechanisms and their impact on system performance for best-effort shared wireless networks.
