In a cognitive radio network, a primary user (PU) shares its spectrum with secondary users (SUs)
temporally and spatially, while allowing for some interference. We consider the problem …

… If the spectrum is highly dynamic, large computational cost is required to update and maintain
the local database. Moreover, it has been found that the AIC framework can be affected by …

… spectrum allocation subproblem, we propose two spectrum allocation strategies named fixed
segmentation and adaptive segmentation … that the proposed dynamic RSA algorithms are …
