Trajectory Design and Link Selection in UAV-Assisted Hybrid Satellite-Terrestrial Network

Mobile relaying is envisioned as a promising technology to alleviate the masking effect in satellite links. Nevertheless, due to the mobility and limited communication range, the network topology in mobile relay networks becomes highly dynamic and time-varying, resulting in increased difficulty of n...
