WiFiUS: Ubiquitous Video over Dynamic Spectrum

This project makes cognitive radio networks suitable as a platform to provide ubiquitous wireless video. The research takes a flexible approach that is applicable to diverse regulations across national boundaries and specifically targets mobile devices. It helps create a cognitive phone, a smartphone with cognitive radio capabilities, to bridge the gap between the technologies behind cognitive radios and real applications.

This project makes cognitive radio networks (CRNs) suitable as a platform to deliver ubiquitous wireless video. It takes a flexible approach that is applicable to diverse regulations across national boundaries. It specifically addresses the major challenges represented by the highly-varying nature of the channel for reliable communications, even in presence of misbehaving users, and the efficient utilization of the available resources for quality video. It finally bridges the gap between the technology behind CRNs and real applications by developing a cognitive phone, i.e., a smartphone with cognitive radio capabilities.
