    • 3-D Placement Schemes of Multiple UAVs in NFP-based Wireless Networks 

      Omri A.; Hasna M.O.; Shakir M.Z.; Shaqfeh M. ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)
      In this paper, we propose two placement strategies of multiple unmanned aerial vehicles (UAVs) in network flying platform (NFP)-based wireless networks. The first strategy is based on a proposed distributed placement ...

    • Analysis of fluctuations of antenna pattern in U-V2X communications 

      Mohammad, Arif; Hasna, Mazen O. ( Elsevier , 2023 , Article)
      The third-generation partnership project (3GPP) defined several scenarios of vehicle-to-everything (V2X) networks such as vehicle-to-vehicle, vehicle-to-pedestrian, and vehicle-to-infrastructure. Unmanned aerial vehicles ...

    • Connectivity Analysis of THz-based UAV-BS Considering Mobile Users 

      Hassan, Heyam; Althunibat, Saud; Khattab, Tamer; Zorba, Nizar ( Institute of Electrical and Electronics Engineers Inc. , 2021 , Conference Paper)
      With the growth of the high data rate demands and the continuous increase in the connected devices and user's equipment, the spectrum resources will not be sufficient. Terahertz (THz) spectrum band provides wide bandwidth ...

    • Energy Harvesting Schemes for UAV based Communications 

      Ali A.; Hasna M.O. ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)
      This paper presents two generic charging and transmission schemes to find the trade-off between the altitude of an Unmanned aerial vehicle (UAV) base station and the acquired harvested energy for maximum coverage area. The ...

    • Modulating Retroreflector Based Free Space Optical Link for UAV-to-Ground Communications 

      Dabiri, Mohammad Taghi; Rezaee, Mohsen; Mohammadi, Leila; Javaherian, Farhang; Yazdanian, Vahid; ... more authors ( IEEE , 2022 , Article)
      Weight reduction and low power consumption are key requirements in the next generation of unmanned aerial vehicle (UAV) networks. Employing modulating retro-reflector (MRR)-based free space optical (FSO) technology is an ...

    • Optimal Trajectory and Positioning of UAVs for Small Cell HetNets: Geometrical Analysis and Reinforcement Learning Approach 

      Dabiri, Mohammad Taghi; Hasna, Mazen; Zorba, Nizar; Khattab, Tamer ( IEEE , 2023 , Article)
      In this paper, a dynamic unmanned aerial vehicle (UAV)-based heterogeneous network (HetNet) equipped with directional terahertz (THz) antennas is studied to solve the problem of transferring massive traffic of distributed ...

    • Real-time Imitation of Autonomous MCG Node using Dual ECG Probing IoT Node Suitable for Delivery by UAV 

      Tariq, Hasan; Abualsaud, Khalid; Yaacoub, Elias; Abualsaud, Rana; Khattab, Tamer; ... more authors ( Institute of Electrical and Electronics Engineers Inc. , 2023 , Conference Paper)
      The gigantic increase in population, social isolation, and mobility constraint lifestyle since the COVID-19 era has resulted in challenges like remote availability of critical bio-instrumentation like magnetocardiography ...

    • Secure AF Relaying in Power-Constrained UAV Networks 

      Samara, Lutfi; AlAbbasi, Abubakr O.; El Shafie, Ahmed; Hamila, Ridha; Al-Dhahir, Naofal ( IEEE , 2021 , Conference Paper)
      This paper proposes a secure amplify-and-forward (AF) relaying scheme in unmanned aerial vehicle (UAV) networks while accounting for the power consumption limitations of UAVs. Since a UAV's battery life is limited, we ...
