We formulate a scheduling problem that takes into account different hardware delays experienced by the secondary users
(SUs) in a centralized cognitive radio network (CRN) while switching to different frequency bands. We propose a polynomial-time
suboptimal algorithm to address our formulated scheduling problem. We evaluate the impact of varying switching delay, number of
frequencies, and number of SUs. Our simulation results indicate that our proposed algorithm is robust to changes in the hardware
spectrum switching delay and its performance is very close to its upper bound. We also compare our proposed method with the
corresponding constant switching delay-based algorithm and demonstrate that our suggestion of taking into account the different
hardware delays while switching to different frequency bands is essential for scheduling in CRNs.
