A Cross-Layer Framework for Multi-Layer-Video Multicast With QoS Requirements in Multirate Wireless Networks

This paper proposes a cross-layer framework for efficient multi-layer-video multicast with rate adaptation and Quality of-Service (QoS) requirements in multirate wireless networks. The authors employ time division multiple access at the physical layer to transmit different video layers data. The multicast sender then dynamically regulates the transmission rate and time-slot allocation based on the Channel State Information (CSI) and loss QoS requirements imposed by upper protocol layers.
