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.

Secrecy Outage Probability Fairness for Intelligent Reflecting Surface-Assisted Uplink Channel [PDF]
, 2022 This paper investigates physical layer security (PLS) in the intelligent reflecting surface (IRS)-assisted multiple-user uplink channel. Since the instantaneous eavesdropper's channel state information (CSI) is unavailable, the secrecy rate can not be ...

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 ...
