2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010
In this paper, we consider secure communications between a single antenna transmitter and a single antenna receiver in the presence of a multiple antenna eavesdropper employing MRC or SDC reception. We show that an M-antenna eavesdropper performing SDC reception has precisely the same degrading effect on secrecy as M single antenna eavesdroppers under ...

Secrecy outage probability of cognitive decode-and-forward relay networks
2016 IEEE International Conference on Communications Workshops (ICC), 2016This 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.

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 relay networking in multiple destination and eavesdropper scenarios
2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014This paper investigates the secrecy outage probability of multicast cooperative relay networking in the presence of multi-destination and multi-eavesdropper nodes. The study is carried out in a multicast relay communication scenario whereby multi-eavesdropper nodes attempt to overhear the source message.

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 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 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.

Minimizing Secrecy Outage Probability in Multiuser Wireless Systems With Stochastic Traffic
IEEE Transactions on Vehicular Technology, 2017We first extend the definition of the secrecy outage probability to wireless systems with adaptive transmission rates and secrecy rates. Then, we consider a scheduling problem in the aforementioned system, jointly considering the reliability, security, and stability, where the scheduler tries to allocate wireless resources to the legitimate users ...
