Connecting Space Missions Through NGSO Constellations: Feasibility Study
Houcine Chougrani, Oltjon Kodheli, Ali Georganaki +6
A satellite internet provider (e.g., Starlink, OneWeb, O3b mPOWER), despite possessing the capability to provide internet services to on-ground users in a global scale, can dramati…
Multi-layer Space Information Networks: Access Design and Softwarization
Hayder Al-Hraishawi, Mario Minardi, Houcine Chougrani +3
In this paper, we propose an approach for constructing a multi-layer multi-orbit space information network (SIN) to provide high-speed continuous broadband connectivity for space m…
NB-IoT via LEO satellites: An efficient resource allocation strategy for uplink data transmission
O. Kodheli, N. Maturo, S. Chatzinotas +2
In this paper, we focus on the use of Low-Eart Orbit (LEO) satellites providing the Narrowband Internet of Things (NB-IoT) connectivity to the on-ground user equipment (UEs). Conve…
