Modeling and Analysis for Proactive-Decision Spectrum Handoff in Cognitive Radio Networks
— Spectrum handoff occurs when the primary users appear in the licensed band occupied by the secondary users. Spectrum handoff procedures aim to help the secondary users to vacat...

Allocating dynamic time-spectrum blocks in cognitive radio networks
A number of studies have shown the abundance of unused spectrum in the TV bands. This is in stark contrast to the overcrowding of wireless devices in the ISM bands. A recent trend...
