T20: Quality-Driven Cross-Layer Design for Multimedia Communications

Presenters: Song Ci, University of Nebraska at Lincoln
Haohong Wang, Marvell Semiconductors



Abstract

Multimedia traffic is delay-sensitive loss-insensitive which is much different from the traditional Internet data traffic. This fact indicates the need of a whole new system and network design. Recently, cross-layer design has become a popular design methodology for enhancing Quality-of-Service over various communication networks. However, most existing cross-layer designs are mainly focusing on improving network QoS in terms of throughput, delay, and jitter; user perceived quality has long been ignored in current multimedia communications. Furthermore, most existing cross-layer designs take the piecemeal approach and lack of a systematic framework of modeling and optimization, leading to suboptimal solutions and/or proprietary designs. Since for most multimedia communications, user perceived quality is the ultimate goal of communications. Thus, quality-driven cross-layer design is one of the enable technologies to the next-generation quality-aware service-oriented multimedia networks.

The aim of this tutorial is to bring together the state-of-the-art research contributions that address the various aspects of quality-driven cross-layer designs for multimedia communications. Contents of interest include:
• Quality-driven cross-layer control and optimization framework
• Cross-layer behavior characterization
• Quality-driven cross-layer design architecture
• Analytical modeling and simulation of quality-driven cross-layer design
• Quality-driven resource management, scheduling, and admission control
• Quality-driven cross-layer MAC and routing protocols
• Content-sensitive quality-aware cross-layer design
• Quality-driven cross-layer design for TCP rate control
• Quality-aware cross-layer design for P2P streaming
• Quality-aware cross-layer optimized cooperative communications
• Design, implementation, and test-bed/experimental results of quality-driven cross-layer design
• Standardization issues and status reports from various standards organizations
