DOI: 10.1007/s11276-017-1446-9
Abstract: Cognitive radio technology provides opportunistic wireless spectrums access for the secondary users (SUs) while primary users (PUs) are dormant. By emergence of a PU in the cognitive radio networks, SUs are required to vacant the… read more here.

DOI: 10.1109/lcomm.2021.3137809
Abstract: In cognitive radio networks (CRNs), spectrum handoff techniques help the interrupted secondary user (SU) vacate the licensed channel and seek for another suitable channel to resume its unfinished transmission. However, multiple interruptions from primary users… read more here.
