Aidos: A Hybrid Optimization Algorithm for Beam Hopping Scheduling in NGSO Mega-Constellations
Lingkai Zhao, Zhe Chen, Kun Qiu +1
With the rapid proliferation of non-geostationary orbit (NGSO) mega-constellations, beam hopping (BH) has become indispensable for resource scheduling in multi-satellite, multi-cov…
Agon: A Semi-Supervised Framework for Robust Satellite Interference Detection
Boyu Yang, Chunyu Yang, Zhe Chen +2
The rapid expansion of non-geostationary orbit (NGSO) satellites alongside existing geostationary orbit (GSO) systems has intensified spectrum congestion and inter-system interfere…
Eunomia: A Multicontroller Domain Partitioning Framework in Hierarchical Satellite Network
Qi Zhang, Kun Qiu, Zhe Chen +4
With the rise of mega-satellite constellations, the integration of hierarchical non-terrestrial and terrestrial networks has become a cornerstone of 6G coverage enhancements. In th…
Tyche: A Hybrid Computation Framework of Illumination Pattern for Satellite Beam Hopping
Ziheng Yang, Kun Qiu, Zhe Chen +2
High-Throughput Satellites (HTS) use beam hopping to handle non-uniform and time-varying ground traffic demand. A significant technical challenge in beam hopping is the computation…
Dora: A Controller Provisioning Strategy in Hierarchical Domain-based Satellite Networks
Qiyuan Peng, Qi Zhang, Yue Gao +1
The rapid proliferation of satellite constellations in Space-Air-Ground Integrated Networks (SAGIN) presents significant challenges for network management. Conventional flat networ…
Stabilizing and Optimizing Inter-Shell Routing in LEO Networks with Integrated Routing Cost
Yaojia Wang, Qi Zhang, Kun Qiu +1
The low Earth orbit (LEO) mega-constellation network (LMCN), which uses thousands of satellites across multi-shell architectures to deliver different services, is facing challenges…
