Secrecy Outage Probability in Backscatter Communication Systems With Tag Selection

IEEE Wireless Communications Letters, 2021
In this letter, we propose a tag selection scheme to enhance the security transmission in a passive backscatter communication system with multiple tags and one eavesdropper, and analyze the secrecy outage probability (SOP). In particular, considering a practical non-linear energy harvesting model, we first determine the optimal dynamic reflection ...

Improving Secrecy Outage Probability with Symbol Extension

2014 IEEE 79th Vehicular Technology Conference (VTC Spring), 2014
This paper reveals symbol extension is capable of improving secrecy performance in the multiple-input single-output (MISO) wiretap channel. We propose a symbol extension scheme jointly with the existing beamforming and artificial noise generation strategy to exploit the time variation of fading channel.

Secrecy Outage Probability in Multi-RAT Heterogeneous Networks

IEEE Communications Letters, 2016
Practical difficulty in examining all base stations (BSs) to choose the best one providing secure transmission in heterogeneous networks (HetNets), we impose a BS association constraint in this letter that the BSs providing an average received signal power at the legitimate user greater than a predetermined receiving threshold can be candidate serving ...

Secrecy outage probability of wirelessly powered wiretap channels

2016 24th European Signal Processing Conference (EUSIPCO), 2016
This paper considers a wirelessly powered wiretap channel, where an energy constrained information source, powered by a dedicated power beacon, communicates with a legitimate user in the presence of a passive eavesdropper. The source is assumed to have multiple antennas, while the other three nodes are equipped with a single antenna each. Considering a

Secrecy Outage Probability of Hybrid Satellite-Terrestrial Relay Networks

GLOBECOM 2017 - 2017 IEEE Global Communications Conference, 2017
In this paper, we consider a hybrid satellite- terrestrial relay network (HSTRN) composed of a geostationary satellite, a terrestrial destination and multiple terrestrial relays in the presence of an eavesdropper, where the satellite transmits its data to the terrestrial destination via decode-and- forward (DF) relays while the secure transmission from

Secrecy outage probability of UAV-aided selective relaying networks

2017 Ninth International Conference on Ubiquitous and Future Networks (ICUFN), 2017
In this work, we analyze the secrecy outage probability of unmanned aerial vehicle (UAV)-aided selective relaying networks with M UAV-transmitters (UTs), N UAV-relays(URs), and K collaborative UAV-eavesdroppers (UEs). In the main channel, the best UT-UR pair is selected to transmit the source message to the destination, while unreliable ground-to-air ...

Secrecy Outage Probability Analysis over Malaga-Malaga Fading Channels

2018 IEEE International Conference on Communications (ICC), 2018
As a novel statistical model, Malaga distribution is proposed recently, which covers many commonly used fading models as special cases. The secure transmission of information over the Malaga fading channels has not been discussed in literature.

Secrecy outage probability of cognitive decode-and-forward relay networks

2016 IEEE International Conference on Communications Workshops (ICC), 2016
This paper investigates the secrecy performance of cognitive decode-and-forward (DF) relay networks with multiple primary users (PUs) receivers, one secondary user (SU) source, multiple SU relays, one SU destination and one SU eaves-dropper over Nakagami-m fading channels.
