Abstract : This paper evaluates the outage probability of cognitive relay networks while adhering to the interference constraint on the primary user, the limited amount of interference which the primary user can tolerate. In the relaying transmission, the relay selection critically affects the performance of relaying transmission and the conventional relay selection criteria are not suitable in cognitive relay networks because of the interference constraint.
Hence, the relay selection criterion for cognitive relay networks is proposed and using it, we derive the outage probability. Based on the analysis, we also define the conditions that the relaying transmission achieves better performance in outage probability than the direct transmission. Finally, it is verified that the distance ratio of interfering link to relaying link, the interference threshold as well as the target data rate affect the superiority to relaying transmission compared to the direct transmission in cognitive relay networks.
