Hypernetworks based Radio Spectrum Profiling in Cognitive Radio Networks

This paper presents a novel concept of active radio spectrum profiling f or C ognitive R adio ( CR) networks using evolutionary hypernetworks. Spectrum profiling enables cognitive radio nodes to abstract and predict usable spectrum opportunities in pre-defined P rimary U sers ( PU) c hannels. T he P U c hannels a re actively monitored through spectrum sensing and the resulting binary time serie...

Issues and Challenges in Spectrum management in Cognitive Radio Networks

Cognitive radio is a revolutionary technology that allows efficient, adaptable and intelligent use of spectrum without causing interference to the current licensed users. For cognitive radio adaptability, optimal usability and the power to evolve are the major factors that set apart an evolutionary machine. This paper introduces the concept of spectrum and network heterogeneity in case of cogni...

A Survey of Spectrum Prediction Techniques for Cognitive Radio Networks

Cognitive radio networks provide an opportunity for unlicensed users (secondary users) to use the allocated spectrum band when not in use by legitimate users (primary users). To use a channel or spectrum, it is required to sense the channel for the presence of primary user which is called Spectrum Sensing. In order to reduce the sensing time of spectrum and to determine the state of the channel...
