Planning Approach to Dynamic Spectrum Access in Cognitive Radio Networks
Source: University of Maryland
Over the past few years, significant effort has been put into various treatments of dynamic spectrum access. This paper has resulted in a many protocols and heuristic techniques for coexistence between primary and secondary users in a frequency band. However, none of these approaches has resulted in a description suitable for implementation on a general purpose cognitive engine. As a result, devices implementing these algorithms cannot truly be called "Cognitive radios" as they are not controlled by a cognitive engine. This paper focuses on translating the basic semantics of dynamic spectrum access into the Action Description Language (ADL), and in particular the primary-prioritized Markov approach to dynamic spectrum access.
