| Summary: |
In this paper, the secrecy performance of a dual-hop mixed radio-frequency/underwater optical wireless communication (RF/UOWC) system is investigated. The considered system consists of one single antenna source node (S) communicating with one destination node (D), considered as the legitimate receiver, through the help of one amplify-and-forward (AF) relay node R equipped with multiple antennas for reception. Specifically, the relay receives the incoming signal from S via an RF link, applies maximal-ratio combining (MRC) technique, amplifies the output combined signal with a fixed gain, and then forwards it
to D via an UOWC link. The transmission protocol is performed under the eavesdroppers’ attempt to overhear the RF link (i.e., SR). We derive an exact closed-form expression for the secrecy intercept probability (IP) in terms of the Fox’s H-function, or in terms of the Meijer’s G-function as a particular case. The derived secrecy performance metric is evaluated in terms of various channel and system parameters, and corroborated by
Monte-Carlo simulation method. Our derived analytical formulas present an efficient tool to highlight the impact of some system and channel parameters on the secrecy performance, namely the number of relay antennas, number of eavesdropping nodes, relay gain, fading severity of RF links, and water turbulence severity
of the UOWC link. |
