Towards Federated, Green, and Resilient 6G Non-Terrestrial Networks
Sarath Babu, Victor Baños-Gonzalez, Mario Cordina +20
This study focuses on future Non-Terrestrial Networks (NTN) integrated with Terrestrial Networks (TN) for future 5G/6G systems. NTN envisions a 3D architecture, where Low Earth Orb…
Twin-Fidelity-Aware Resolution of Direct xApp Conflicts in Open RAN
Akram Almohammedi, Mohammed Balfaqih, Sam Darshi +2
Open Radio Access Network (O-RAN) allows independently developed xApps to control RAN functions through the Near-Real-Time RAN Intelligent Controller (Near-RT RIC). When xApps with…
Cross-Slice Co-Location Risk-Aware SFC Provisioning in Multi-Slice LEO Satellite Networks
Mohammed Mahyoub, Wael Jaafar, Sami Muhaidat +1
We address cross-slice co-location risk in multi-slice low Earth orbit (LEO) satellite edge networks, where virtual network functions (VNFs) from different network slices sharing t…
Computing in Integrated Terrestrial and Non-Terrestrial Networks: A Comprehensive Survey
Hoe Ziet Wong, Insaf Rzig, Safwan Alfattani +1
The rapid growth of Internet-of-things (IoT) devices, smart vehicles, and other connected objects is driving demand for ubiquitous connectivity and intensive computing capacity. 5G…
A Novel Energy-Efficient Cross-Layer Design for Scheduling and Routing in 6TiSCH Networks
Ahlam Hannachi, Wael Jaafar, Salim Bitam +1
The 6TiSCH protocol stack plays a vital role in enabling reliable and energy-efficient communications for the Industrial Internet of Things (IIoT). However, it faces challenges, in…
Market Driven Multi-domain Network Service Orchestration in 5G Networks
Mouhamad Dieye, Wael Jaafar, Halima Elbiaze +1
The advent of a new breed of enhanced multimedia services has put network operators into a position where they must support innovative services while ensuring both end-to-end Quali…
FLSTRA: Federated Learning in Stratosphere
Amin Farajzadeh, Animesh Yadav, Omid Abbasi +2
We propose a federated learning (FL) in stratosphere (FLSTRA) system, where a high altitude platform station (HAPS) facilitates a large number of terrestrial clients to collaborati…
iTUAVs: Intermittently Tethered UAVs for Future Wireless Networks
Nesrine Cherif, Wael Jaafar, Evgenii Vinogradov +3
We propose the intermittently tethered unmanned aerial vehicle (iTUAV) as a tradeoff between the power availability of a tethered UAV (TUAV) and the flexibility of an untethered UA…
Sustaining Dynamic Traffic in Dense Urban Areas with High Altitude Platform Stations (HAPS)
Cihan Emre Kement, Ferdi Kara, Wael Jaafar +4
The impact of information and communication technologies on global energy consumption is increasing every year, and mobile networks account for a significant portion of it. More th…
Joint Caching and Resource Allocation in D2D-Assisted Wireless HetNet
Wael Jaafar, Amina Mseddi, Wessam Ajib +1
5G networks are required to provide very fast and reliable communications while dealing with the increase of users traffic. In Heterogeneous Networks (HetNets) assisted with Device…
Opportunistic Adaptive Relaying in Cognitive Radio Networks
Wael Jaafar, Wessam Ajib, David Haccoun
Combining cognitive radio technology with user cooperation could be advantageous to both primary and secondary transmissions. In this paper, we propose a first relaying scheme for…
A Novel Relay-Aided Transmission Scheme in Cognitive Radio Networks
Wael Jaafar, Wessam Ajib, David Haccoun
In underlay cognitive radio networks, unlicensed secondary users are allowed to share the spectrum with licensed primary users when the interference induced on the primary transmis…
