ML-based Handover Prediction and AP Selection in Cognitive Wi-Fi Networks
Muhammad Asif Khan, Ridha Hamila, Adel Gastli +2
Device mobility in dense Wi-Fi networks offers several challenges. Two well-known problems related to device mobility are handover prediction and access point selection. Due to the…
Security-Enhanced SC-FDMA Transmissions Using Temporal Artificial-Noise and Secret-Key Aided Schemes
Mohamed F. Marzban, Ahmed El Shafie, Naofal Al-Dhahir +1
We investigate the physical layer security of uplink single-carrier frequency-division multiple-access (SC-FDMA) systems. Multiple users, Alices, send confidential messages to a co…
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…
Cooperative Access Schemes for Efficient SWIPT Transmissions in Cognitive Radio Networks
Ahmed El Shafie, Naofal Al-Dhahir, Ridha Hamila
We investigate joint information and energy cooperative schemes in a slotted-time cognitive radio network with a primary transmitter-receiver pair and a set of secondary transmitte…
Sparsity-Cognizant Multiple-Access Schemes for Large Wireless Networks With Node Buffers
Ahmed El Shafie, Naofal Al-Dhahir, Ridha Hamila
This paper proposes efficient multiple-access schemes for large wireless networks based on the transmitters' buffer state information and their transceivers' duplex transmission ca…
