Wireless communications is one of the fastest growing fields in the world; however this creates a problem since all wireless signals are fighting for the same limited amount spectrum in any given space. The underutilization of licensed spectrum has created a need for a new way to use it. Cognitive Radio Networks and Dynamic Spectrum Access are a solution to this problem. By opportunistically using spectrum, devices can gain access to more wireless bandwidth while not violating FCC regulations. The concepts of Cognitive Radio Networks and Dynamic Spectrum Access are very new topics and have yet to be fully explored. One of the current goals in this area is adapting existing concepts in networking algorithms to be aware of and to take advantage of a Dynamic Spectrum Access environment. Awareness and using cross-layer design enables opportunistic use of the spectrum and allows devices to take full advantage of the nature of the Dynamic Spectrum Access environment. This thesis explores some existing solutions to the Dynamic Spectrum Access problem, and uses them as inspiration to create a Link-quality-aware Graph Model for Cognitive Radio Network Routing Topology Management.
