Secrecy Outage Probability of SWIPT-OFDMA Schemes with Transmit Antenna Selection

open access: yes2023 31st Signal Processing and Communications Applications Conference (SIU), 2023
This study examines the wireless communications secrecy performance of multi-user (MU) simultaneous wireless information and power transfer (SWIPT) scheme employing transmit antenna selection (TAS) and maximal-ratio combining (MRC). In order to address the user scheduling requirement of MU-SWIPT scheme, orthogonal frequency-division multiple access ...

Secrecy outage probability of inter‐vehicular cognitive radio networks

open access: yesInternational 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.

Artificial-Noise Aided Secure Transmission in Large Scale Spectrum Sharing Networks [PDF]

open access: yes, 2016
We investigate beamforming and artificial noise generation at the secondary transmitters to establish secure transmission in large scale spectrum sharing networks, where multiple noncolluding eavesdroppers attempt to intercept the secondary transmission.

Enhancing wireless security via optimal cooperative jamming [PDF]

open access: yes, 2012
In this work, we analyze the secrecy rate in a cooperative network, where a source node is assisted by relay nodes via cooperative jamming for delivering a secret message to the destination in the presence of an eavesdropper node.

Selection of Jammer and Analysis on Secrecy Outage Probability for WANETs

open access: yesProcedia 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 ...
