Secure Beamforming in Full-Duplex SWIPT Systems With Loopback Self-Interference Cancellation
Yanjie Dong, Ahmed El Shafie, Md. Jahangir Hossain +3
Security is a critical issue in full duplex (FD) communication systems due to the broadcast nature of wireless channels. In this paper, joint design of information and artificial n…
On the Monetary Loss Due to Passive and Active Attacks on MIMO Smart Grid Communications
Ahmed El Shafie, Hamadi Chihaoui, Ridha Hamila +3
We consider multiple source nodes (consumers) communicating wirelessly their energy demands to the meter data-management system (MDMS) over the subarea gateway(s). We quantify the…
Optimal Random Access and Random Spectrum Sensing for an Energy Harvesting Cognitive Radio
Ahmed El Shafie, Ahmed Sultan
We consider a secondary user with energy harvesting capability. We design access schemes for the secondary user which incorporate random spectrum sensing and random access, and whi…
Cooperative Cognitive Relaying with Ordered Cognitive Multiple Access
Ahmed El Shafie, Ahmed Sultan
We investigate a cognitive radio system with two secondary users who can cooperate with the primary user in relaying its packets to the primary receiver. In addition to its own que…
