(English Abstract)
In this paper, we propose a new relay selection scheme which can decrease the secrecy outage probability in a relay communication network with multiple relays and an eavesdropper. In the conventional relay selection scheme, a relay transmits jamming signal toward an eavesdropper to decrease the successful decoding probability of the eavesdropper. The coventional scheme has a critical problem that the successful decoding probability of a receiver also decreases. The new relay selection scheme proposed in this paper can significantly enhance the secrecy outage probability by selecting a pair of relays which can increase the successful decoding probability of the receiver while decreasing the successful decoding probability of the eavesdropper. We performed extensive computer simulation based on Monte-Carlo. The simulation results reveal that the proposed relay selection scheme can improve the secrecy outage probability by 10 to 50 times compared to the existing relay selection scheme.
