… In this section, the effect of the primary user traffic on the sensing-throughput tradeoff is
examined. For all the results, the total frame duration is set to 30 ms and the SNR of the …

… and the signal-tonoise ratio of primary user at the secondary receiver is −20dB, the optimal
sensing time achieving the highest throughput while maintaining 90% detection probability is …

… Appropriate relaying improves the throughput of the primary users and can increase the …
throughput of the primary user for the proposed schemes and for different number of users. The …

… In this paper, the primary goal is to increase the system throughput. The main idea is to
achieve higher system throughput by increasing the transmission interval within the frame. This is …

… throughput are vital to achieve good performance in such systems. In this paper, we consider
a set of primary users that … We assess the effect of these demands on primary user activity, …

… Also, we use subscripts p and s to denote primary and secondary network parameters, …
impact on the primary throughput. As mentioned earlier, the primary throughput can be protected …

… throughput gain of the network mainly depends on the throughput gain of SUs because the
throughput of … we consider the throughput of cognitive radio network as the throughput of SUs …

… primary packets per joule without and with cooperation. • We characterize the maximum
secondary throughput of … In Section IV, we discuss the stablethroughput region of the proposed …

… Based on the proposed MAC protocol, we derive the stable throughput expressions of
each primary user with secondary relaying. We also achieve the stable network constraints of …

… are allowed to access the spectrum licensed to primary users only when the primary
users do not occupy the spectrum. This approach comes from the idea of opportunistic …
