Channel Reuse for Backhaul in UAV Mobile Networks with User QoS Guarantee

no code implementations19 Jan 2023 Mohammadsaleh Nikooroo, Zdenek Becvar, Omid Esrafilian, David Gesbert

In this paper, we study the problem of sum downlink capacity maximization in FlyBS-assisted networks with mobile users and with a consideration of wireless backhaul with channel reuse while a minimum required capacity to every user is guaranteed.

Sum Capacity Maximization in Multi-Hop Mobile Networks with Flying Base Stations

no code implementations21 Oct 2022 Mohammadsaleh Nikooroo, Omid Esrafilian, Zdenek Becvar, David Gesbert

To this end, we propose an analytical approach based on an alternating optimization of the FlyBSs' 3D positions as well as the association of the users to the FlyBSs over time.
