Experiences Implementing Cognitive Radio Control Algorithms

In recent years, several algorithms for controlling cognitive radio platforms have been proposed. In this paper, we review the existing approaches that have been developed for cognitive radio control algorithms and extract the common sensing and control requirements for those algorithms. We also briefly discuss the challenges of defining representative testing scenarios. We then synthesize our experience implementing cognitive radio control algorithms and extract a set of pragmatic issues challenging researchers in cognitive radios. We conclude with a set of open questions and problems and discuss implications for future research.
