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.

(书)现代通信系统使用MATLAB第三章(ALLIANCES is a recently proposed cooperative random access
protocol for wireless networks. In this paper we modify the
original model to include user location information. We also
derive pair-wise error probability (PEP) under Rayleigh flat
fading channel and a power-law attenuation environment.
Based on the PEP analysis we propose an optimal relay
selection scheme, which achieves significant throughput gains as
compared to the random relay selection scheme in the original
ALLIANCES.)
