Self-Tuning Spectral Clustering for Adaptive Tracking Areas Design in 5G Ultra-Dense Networks
Brahim Aamer, Hatim Chergui, Nouamane Chergui +4
In this paper, we address the issue of automatic tracking areas (TAs) planning in fifth generation (5G) ultra-dense networks (UDNs). By invoking handover (HO) attempts and measurem…
Classification Algorithms for Semi-Blind Uplink/Downlink Decoupling in sub-6 GHz/mmWave 5G Networks
Hatim Chergui, Kamel Tourki, Redouane Lguensat +3
Reliability and latency challenges in future mixed sub-6 GHz/millimeter wave (mmWave) fifth generation (5G) cell-free massive multiple-input multiple-output (MIMO) networks is to g…
Securing Untrusted Full-Duplex Relay Channels in the Presence of Multiple External Cluster-Based Eavesdroppers
Ahmed El Shafie, Asma Mabrouk, Kamel Tourki +2
This letter investigates the physical layer security in a wireless cooperative network where communication is assisted by a full-duplex (FD) untrusted relay in the presence of mult…
Probabilistic Jamming/Eavesdropping Attacks to Confuse a Buffer-Aided Transmitter-Receiver Pair
Ahmed El Shafie, Kamel Tourki, Zhiguo Ding +1
We assume that a buffer-aided transmitter communicates with a receiving node in the presence of an attacker. We investigate the impact of a radio-frequency energy-harvesting attack…
Secret-Key-Aided Scheme for Securing Untrusted DF Relaying Networks
Ahmed El Shafie, Ahmed Sultan, Asma Mabrouk +2
This paper proposes a new scheme to secure the transmissions in an untrusted decode-and-forward (DF) relaying network. A legitimate source node, Alice, sends her data to a legitima…
Energy Efficiency in Cell-Free Massive MIMO with Zero-Forcing Precoding Design
L. D. Nguyen, T. Q. Duong, H. Q. Ngo +1
We consider the downlink of a cell-free massive multiple-input multiple-output (MIMO) network where numerous distributed access points (APs) serve a smaller number of users under t…
An Artificial-Noise-Aided Hybrid TS/PS Scheme for OFDM-Based SWIPT Systems
Ahmed El Shafie, Kamel Tourki, Naofal Al-Dhahir
We propose a new artificial-noise aided hybrid time-switching/power-splitting scheme for orthogonal frequency-division multiplexing (OFDM) systems to securely transmit data and tra…
Performance of Opportunistic Fixed Gain Bidirectional Relaying With Outdated CSI
Fahd Ahmed Khan, Kamel Tourki, Mohamed-Slim Alouini +1
This paper studies the impact of using outdated channel state information for relay selection on the performance of a network where two sources communicate with each other via fixe…
Accurate Performance Analysis of Opportunistic Decode-and-Forward Relaying
Kamel Tourki, Hong-Chuan Yang, Mohamed-Slim Alouni
In this paper, we investigate an opportunistic relaying scheme where the selected relay assists the source-destination (direct) communication. In our study, we consider a regenerat…
