| Abstract: | We consider a cognitive radio network (CR) consisting of a secondary transmitter (ST), a secondary destination (SD), and multiple secondary relays (SRs) in the presence of an interceptor, where the ST transmits to the SD using the SRs while the interceptor attempts to intercept the secondary transmission. We rely on careful relay selection to protect the ST-SD transmission from the interceptor, using both single and multiple relay selection. To be precise, single-relay selection selects only the "best" SR to support the secondary transmission, while multiple SRs are used in multi-relay selection to simultaneously relay the transmission from ST to SD. The proposed single and multi relay selection schemes are analyzed using intercept and outage probability for the secondary user transmission based on the realistic spectrum detection. We also evaluate the performance of classical direct transmission method to compare with the proposed relay selection methods. It is shown that the outage performance of the direct transmissionmethod and relay selection methods improves when the outage probability requirement is relaxed, and vice versa. Moreover, we show that the SRT (Security Reliability Trade off) of the single-relay and multi-relay selection schemes are generally better than that of the classical direct transmission, which explicitly demonstrates the advantage of the proposed relay selection in protecting the secondary transmissions from eavesdropping attacks. |
