AdaptSky: A DRL Based Resource Allocation Framework in NOMA-UAV Networks
Ahmed Benfaid, Nadia Adem, Bassem Khalfi
Unmanned aerial vehicle (UAV) has recently attracted a lot of attention as a candidate to meet the 6G ubiquitous connectivity demand and boost the resiliency of terrestrial network…
Dynamic Spectrum Sharing in the Age of Millimeter Wave Spectrum Access
Bechir Hamdaoui, Bassem Khalfi, Nizar Zorba
Next-generation wireless networks are facing spectrum shortage challenges, mainly due to, among other factors, the projected massive numbers of IoT connections and the emerging ban…
Mixed RF/FSO Relaying Systems with Hardware Impairments
Elyes Balti, Mohsen Guizani, Bechir Hamdaoui +1
In this work, we provide a detailed analysis of a dual-hop fixed gain (FG) amplify-and-forward relaying system, consisting of a hybrid radio frequency (RF) and free-space optical (…
Aggregate Hardware Impairments Over Mixed RF/FSO Relaying Systems With Outdated CSI
Elyes Balti, Mohsen Guizani, Bechir Hamdaoui +1
In this paper, we propose a dual-hop RF (Radio-Frequency)/FSO (Free-Space Optical) system with multiple relays employing the Decode-and-Forward (DF) and Amplify-and-Forward (AF) wi…
Exploiting wideband spectrum occupancy heterogeneity for weighted compressive spectrum sensing
Bassem Khalfi, Bechir Hamdaoui, Mohsen Guizani +1
Compressive sampling has shown great potential for making wideband spectrum sensing possible at sub-Nyquist sampling rates. As a result, there have recently been research efforts t…
Responsive Content-Centric Delivery in Large Urban Communication Networks: A LinkNYC Use-Case
Hassan Sinky, Bassem Khalfi, Bechir Hamdaoui +1
Large urban communication networks such as smart cities are an ecosystem of devices and services cooperating to address multiple issues that greatly benefit end users, cities and t…
