Meanwhile, queueing analysis methods have been applied to study the throughput and/or delay performances of buffered cognitive relay systems [9, 11, 12] . ...
In such a system, a successful packet delivery may require two idle timeslots, one for the S-D direct transmission and one for the retransmission carried out by the relays. ...
While the ICaD-ARQ-QS scheme can achieve a tradeoff between the average throughput and the end-to-end delay by adjusting the queue threshold. ...
