Description:

This project focuses on the emerging Dynamic Spectrum Access (DSA) Wireless Mesh Networks (WMNs). Cross-layer design is strongly needed for such a network due to its two special features: dynamic spectrum availability and spectrum heterogeneity. We are conducting a comprehensive study on cross-layer optimization for DSA WMNs, and designing networking protocols under its guidance. Specifically, we concentrate on the bottom four layers of the network stack and seek joint congestion control, routing, spectrum sharing, and power control solutions with the objective of maximizing throughput, achieving certain fairness, and providing QoS support.
