Cognitive radios are devices which have the ability to adjust their communication parameters based on observations of the surrounding environment. Cognitive Radio Networks (CRNs) are envisioned for use in licensed communication channels, operating on ‘borrowed’ spectrum in a non-interference manner. This technology has the potential to revolutionize wireless communication and alleviate the overuse of certain unlicensed communication bands. Research in this area is relatively new, and significant effort must be placed into researching how cognitive radio devices can operate with a reasonably low effect on the licensed spectrum users. In this dissertation, three areas are researched, focusing on practical mechanisms which can provide service to CRNs while minimizing the impact on licensed users. First, a cross-layer routing selection algorithm is proposed which utilizes fuzzy-logic modeling to gracefully map network quality of service (QoS) requirements and CRN-aware requirements to a route cost function. The second method looks into utilizing cooperation between licensed users and cognitive radios to facilitate CRN communication while improving the throughput of licensed users. Finally, the use of directional transmissions is researched. Directional transmissions have the potential to significantly reduce the impact of cognitive radios on licensed users, however, directional transmissions introduce many complexities to the realm of wireless communication. Some of these complexities will be explored, along with practical and implementable solutions.
