Communication by Whispers Paradigm for Short Range Communication in Cognitive Radio Networks Using Interference Based MAC Sensing for Opportunity Discovery
With ever increasing demand for efficiency and increased throughput over the wireless domain, the authors have now reached a point where in a method for efficient utilization of the electromagnetic spectrum is in demand. Cognitive radio provides one with a way in which this demand could be catered, it does so by using devices which autonomously adjust their communication parameters to adapt to the external environment. However, the most critical of this entire technology is the parameter relating to the Spectrum Sensing aspects. In order for cognitive radio devices to properly configure and identify the presence of a primary carrier in a communication mode, spectrum sensors and efficient sensing algorithms are required.
