Threat-Aware Energy-Efficient Deployment for Dynamic UAV Networks: A Multi-Agent RL Approach
Faisal Al-Kamali, Hussein A. Ammar, Francois Chan +3
Ensuring operational safety in threat-prone environments remains a critical challenge for multi-UAV networks serving as aerial base stations. This paper proposes an efficient frame…
Enhancing UAV Trajectory and Communications Through Vision-Inertial Tracking
Abdallah S. Ghazy, Hussein A. Ammar, James Bayes +1
In this paper, we propose an energy-efficient and reliable communication system for non-terrestrial networks deployed in dynamic GPS-denied wireless environments, enabled by a Visi…
Fronthaul Network Planning for Hierarchical and Radio-Stripes-Enabled CF-mMIMO in O-RAN
Anas S. Mohammed, Krishnendu S. Tharakan, Hussein A. Ammar +2
The deployment of ultra-dense networks (UDNs), particularly cell-free massive MIMO (CF-mMIMO), is mainly hindered by costly and capacity-limited fronthaul links. This work proposes…
UAV-Mounted Aerial Relays in Military Communications: A Comprehensive Survey
Faisal Al-Kamali, Francois Chan, Hussein A. Ammar +2
Relays are pivotal in military communication networks, expanding coverage and ensuring reliable connectivity in challenging operational environments. While traditional terrestrial…
Remote Interference Mitigation through Null Precoding and Fractional Programming
Xuyang Sun, Hussein A. Ammar, Israfil Bahceci +3
With the rapid deployment of 5G systems, remote interference (RI) caused by atmospheric ducting has emerged as an occasional, but critical challenge. This phenomenon occurs when th…
Handoff Design in User-Centric Cell-Free Massive MIMO Networks Using DRL
Hussein A. Ammar, Raviraj Adve, Shahram Shahbazpanahi +2
In the user-centric cell-free massive MIMO (UC-mMIMO) network scheme, user mobility necessitates updating the set of serving access points to maintain the user-centric clustering.…
