In this paper, we consider a hybrid satellite-terrestrial relay network (HSTRN) composed of a geostationary satellite, a terrestrial destination and multiple terrestrial relays in the presence of an eavesdropper, where the satellite transmits its data to the terrestrial destination via decode-and-forward (DF) relays while the secure transmission from relay to destination may leak to the eavesdropper. We explore the physical-layer security against eavesdropping attacks in HSTRN and propose the optimal relay selection scheme for improving the transmission security. Additionally, the classic round-robin scheduling is also considered to a benchmark scheme. Furthermore, the closed-form expressions of secrecy outage probability for both the round-robin scheduling and optimal relay selection schemes are derived. Finally, numerical results show that our proposed scheme generally outperforms the round-robin scheduling in terms of the secrecy outage probability. |
