A Collaboration Incentive Exploiting the Primary-Secondary Systems' Cross Interference for PHY Security Enhancement
Tourki, Kamel; Hasna, Mazen O. ( IEEE , 2016 , Article)We investigate the spectrum sharing possibility as an incentive to enhance the physical layer security. The concept behind is that a legitimate source-destination pair, communicating in the presence of a passive eavesdropper, ... -
Performance analysis of secure AF relay networks using cooperative jamming under outdated CSI
Mabrouk, Asma; Tourki, Kamel; Hasna, Mazen O.; Hamdi, Noureddine ( Institution of Engineering and Technology , 2017 , Article)This paper studies cooperative transmission for securing a two-hop network where the eavesdropper can wiretap the relay channels. With outdated channel state information (CSI), we propose an opportunistic relaying with ... -
Performance enhancement of cognitive relay networks using regression functions
Tourki, Kamel; Hasna, Mazen O. ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In a spectrum sharing relay-aided secondary network, the design objective shifts from minimizing the violation of the primary system constraints when using the outdated channel state information (CSI), to making the best ... -
Proactive spectrum sharing incentive for physical layer security enhancement using outdated CSI
Tourki, Kamel; Hasna, Mazen O. ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)We investigate the spectrum sharing possibility as an incentive to enhancing the physical layer security. The concept behind this is that a legitimate source-destination pair, communicating in the presence of a passive ... -
Securing Untrusted RF-EH Relay Networks Using Cooperative Jamming Signals
El Shafie, Ahmed; Mabrouk, Asma; Tourki, Kamel; Al-Dhahir, Naofal; Hamila, Ridha ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)We propose a new scheme to secure a wireless-powered untrusted cooperative-communication network, where a legitimate source node (Alice) transmits her information messages to a legitimate destination node (Bob) through the ... -
Wireless transmission with cooperation on demand for slow and fast fading environments
Tourki, Kamel; Alouini, Mohamed S.; Hasna, Mazen O. ( IEEE , 2008 , Conference Paper)Mobile users with single antennas can still take advantage of spatial diversity through repetition based cooperative transmission. In this paper, we consider a scheme in which the relay chooses to cooperate only if the ...
