Artificial Noise-Aided User Scheduling From the Perspective of Secrecy Outage Probability
IEEE Transactions on Vehicular Technology, 2018In this correspondence paper, we propose a secure user scheduling scheme, which selects a user for data transmission and an extra user for artificial noise generation in a multiuser single-input and multiple-output wiretap network.

Secrecy Outage Probability of Cooperative Relay Networks with Channel Estimation Error
2018 IEEE Global Communications Conference (GLOBECOM), 2018In this paper, we consider a dual-hop decode-and-forward (DF) relay network which consists of a source, a destination and multiple DF relays in the presence of an eavesdropper, where the source transmits its data to the destination with the help of DF relays while the eavesdropper attempts to tap the relay transmissions.

Secrecy Outage Performance Analysis for Uplink CR-NOMA Systems With Hybrid SIC
IEEE Internet of Things Journal, 2023In the uplink cognitive radio-inspired nonorthogonal multiple access (CR-NOMA) systems, the successive interference cancellation (SIC), and power control (PC) schemes were designed to enhance the outage performance but they lack the capability of ...

Secrecy Outage Probability of Selective Relaying Wiretap Channels with Collaborative Eavesdropping
2015 IEEE Global Communications Conference (GLOBECOM), 2014We analyze the secrecy outage probability of selective relaying wiretap channels with K decode- and-forward (DF) relays and N collaborative eavesdroppers. In the main channel, we consider a two-hop relay network where the best relay is selected to transmit and the relay link is combined with the direct source-to-destination link at the destination.

Secrecy Outage Probability Analysis of Dual-Hop RF-FSO Fixed-Gain Relaying System
International Symposium on Telecommunications, 2018We analyze the secrecy outage probability of a dual-hop radio frequency (RF)-free space optical (FSO) transmission systems. We assume that the eavesdropping occurs at the RF channel which experiences Nakagami-m fading while the FSO link suffers from ...

Security Region Analysis with Artificial Noise Based on Secrecy Outage Probability
MILCOM 2018 - 2018 IEEE Military Communications Conference (MILCOM), 2018This paper analyzes security region with artificial noise (AN) based on secrecy outage probability under the assumption that the eavesdropper's channel state information and location are unknown to the transceiver. By utilizing beamforming, the legitimate receiver transmits the AN in the direction of the legitimate transmitter to impair the ...

Secrecy Outage Probability of a Distributed Multi-Antenna Cooperative Communication System
Wireless Personal Communications, 2016A distributed multi-antenna cooperative communication system with amplify-and-forward mode for secure communication in the presence of an eavesdropper is considered. In the communication system, there is no direct communication link between the transmitter and the intended receiver, and all nodes except relay nodes are equipped with multi-antenna.

Exact Outage Probability of Cooperative Secrecy Transmission: Impact of Unavailable Relays
Wireless Personal Communications, 2015The impact of unavailable relays is a serious issue in cooperative communication schemes, where the operation state of relays affects optimal relay selection. In addition, secure signal transmission is an interesting approach to prevent the wiretapping actions of eavesdropper nodes in a wireless environment.

Secrecy Outage Probability of Multiuser Untrusted Amplify-and-Forward Relay Networks
2017 IEEE 85th Vehicular Technology Conference (VTC Spring), 2017This paper investigates the effect of untrusted relay on the secrecy outage probability of amplify- and-forward relay networks with the help of direct links and multiple users. We consider three selection criteria which are based on the direct and relaying link. The impacts of both the direct and relaying links on SOP performance is studied by deriving

Secrecy Outage Probability for MRC Receiver in Presence of Multiple Antenna Eavesdropper
2018 IEEE 13th International Conference on Industrial and Information Systems (ICIIS), 2018In this paper, we consider a hybrid fading model in which line of sight (LOS) component is available between the transmitter and legitimate receiver and assume that eavesdropper is not in LOS from the transmitter. We analyze probability of existence of secrecy and secrecy outage probability for the case that the channels to the legitimate receiver are $
