Project Description

Towards Rich Multimedia Experience in Emerging Cognitive Radio Networks

This project investigates the problem of enabling rich multimedia services in emerging CR networks. Although highly rewarding, the new dimension of dynamics on channel availability, sensing, and access brings about a whole level of technical challenges. To address these challenges, a novel cross-layer optimization and control approach is employed, complemented with distributed algorithm design and development of an open source CR video testbed. The manifold design trade-offs, multifarious dynamics, scarce resources and, on the other hand, video's tight QoS constraints make the optimization and control approach highly suited for "squeezing" the most out of CR video networks. The three research thrusts include: cross-layer optimization of CR video networks, classical and modern control theory based analysis and design of CR video networks, and experimental research with a CR video testbed and field experiments.
