Delay-optimal spectrum decision method for cognitive network

Delay-optimal spectrum decision method for cognitive network

Spectrum decision was investigated within the confine of spectrum management framework for cognitive radio networks.Sensing errors in PHY layer,outage probability on wireless channel and multiple interruptions of primary user were taken into consideration.Probability-based and sensing-based spectrum...
