Secrecy Outage Probability of Hybrid Satellite-Terrestrial Relay Networks
GLOBECOM 2017 - 2017 IEEE Global Communications Conference, 2017In 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), 2017In 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 for the multiuser downlink with several curious users
2016 IEEE Wireless Communications and Networking Conference, 2016This paper studies the physical layer security in a multi-user downlink, where a single user is selected for secret transmission during each time frame. Current works usually assume a worst case where all unselected users are curious and act as eavesdroppers, and conclude that no multiuser diversity is achievable for secrecy when the number of users is

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.

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 and jamming coverage of UAV-enabled friendly jammer
2017 11th International Conference on Signal Processing and Communication Systems (ICSPCS), 2017In this paper, we examine the secrecy performance of an unmanned aerial vehicle (UAV) equipped with an air-to-ground jammer and a ground communications network comprising a legitimate transmitter-receiver pair and an eavesdropper. We consider two scenarios: stationary UAV jammer and mobile UAV jammer. In the first scenario, we derive the secrecy outage

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 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.

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 $
