A Double-Difference Doppler Shift-Based Positioning Framework with Ephemeris Error Correction of LEO Satellites
Md. Ali Hasan, M. Humayun Kabir, Md. Shafiqul Islam +2
In signals of opportunity (SOPs)-based positioning utilizing low Earth orbit (LEO) satellites, ephemeris data derived from two-line element files can introduce increasing error ove…
Cooperative Learning-Based Framework for VNF Caching and Placement Optimization over Low Earth Orbit Satellite Networks
Khai Doan, Marios Avgeris, Aris Leivadeas +2
Low Earth Orbit Satellite Networks (LSNs) are integral to supporting a broad range of modern applications, which are typically modeled as Service Function Chains (SFCs). Each SFC i…
