Secrecy outage probability of inter‐vehicular cognitive radio networks
International Journal of Communication Systems, 2019 SummaryHerein, we consider an underlay cognitive radio network (CRN) where mobile secondary user wishes to transmit a confidential information to the secondary destination in the presence of an illegitimate eavesdropper which is trying to steal the classified message signal.

Selection of Jammer and Analysis on Secrecy Outage Probability for WANETs
Procedia Computer Science, 2020 Abstract In this paper, we investigate the physical layer security (PLS) in wireless ad hoc networks (WANETs). For fixed transmission distance model, we introduce the jammer selection scheme to enhance the secrecy transmission capacity. The jammer can prevent the eavesdropper from stealing information by sending the interference signal to the ...

Physical-Layer Security Enhancement via Relay-Aided D2D Communications Underlaying Cellular Networks
IEEE Open Journal of the Communications Society, 2020 In this paper, we propose a relay-assisted device-to-device (D2D) communication as an underlay in a cellular network, where two sequential best relay nodes based on different selection criteria are chosen.

Secrecy Outage Probability and Fairness of Packet Transmission Time in a NOMA System [PDF]
IEEE Access, 2020 في هذه الورقة، نقوم بتحليل احتمالية انقطاع السرية (SOP) ونزاهة متوسط وقت نقل الحزمة لنظام الوصول المتعدد غير المتعامد (NOMA) الذي يتكون من محطة قاعدة (BS) واثنين من مستخدمي NOMA القانونيين في وجود جهاز تنصت (EVE). من أجل استخراج الإشارة المتراكبة، يتم اعتبار EVE في وضعين، أي وضع إلغاء التداخل المتتالي (SIC) ووضع إلغاء التداخل المتوازي (PIC). وفقًا لذلك،
