论文摘要
这项工作研究了射频（RF） - Free空间光学（FSO）混合卫星卫星 - 卫星 - 体外网络（SATN）的上行链路传输的保密冲电性能。具体而言，在经过考虑的合作卫星中，地面来源通过启用缓存的空中继电器（R）终端的帮助，将其信息传输到卫星接收器（D），并具有最受欢迎的内容缓存方案，而一组窃听的空中终端（EVES）试图使传播的自由信息过多地进行渗透。此外，RF和FSO传输分别在S-R和R-D链路上采用。考虑到R，D和EVES的随机性以及采用随机几何框架，研究了所考虑的SATN中合作上行链路传播的保密中断性能，并得出了最终端到端保密概率的封闭形式的分析表达。最后，显示蒙特 - 卡洛模拟可以验证我们分析的准确性。
This work investigates the secrecy outage performance of the uplink transmission of a radio-frequency (RF)-free-space optical (FSO) hybrid cooperative satellite-aerial-terrestrial network (SATN). Specifically, in the considered cooperative SATN, a terrestrial source (S) transmits its information to a satellite receiver (D) via the help of a cache-enabled aerial relay (R) terminal with the most popular content caching scheme, while a group of eavesdropping aerial terminals (Eves) trying to overhear the transmitted confidential information. Moreover, RF and FSO transmissions are employed over S-R and R-D links, respectively. Considering the randomness of R, D, and Eves, and employing a stochastic geometry framework, the secrecy outage performance of the cooperative uplink transmission in the considered SATN is investigated and a closed-form analytical expression for the end-to-end secrecy outage probability is derived. Finally, Monte-Carlo simulations are shown to verify the accuracy of our analysis.
