SABM: Adaptive Backup Mechanism for Satellite Services
Within the harsh space environment, satellite failures are common occurrences caused by component failures and natural disaster threats. Consequently, the implementation of a reliability mechanism is crucial to prevent the dissemination of inaccurate ...
Can Orbital Servers Provide Mars-Wide Edge Computing?
Human landing, exploration and settlement on Mars will require local compute resources at the Mars edge. Landing such resources on Mars is an expensive endeavor. Instead, in this paper we lay out how concepts from low-Earth orbit edge computing may be ...
Collaborative Resource Orchestration for On-Orbit Edge Computing in 5G SAGIN
On-orbit edge computing is an important component of the space-air-ground integration network (SAGIN) in the development process of 6G mobile communications. However, it is challenging to explore the collaborative management and scheduling of ...
Internet via Satellite: GEO vs. LEO, OpenVPN vs. Wireguard, and CUBIC vs. BBR
Geostationary (GEO) satellite communication achieves high data rates but relies on Performance Enhancing Proxies to mitigate the negative effects of high latency paths. However, such proxies cannot be applied if the transport protocol headers are ...
Energy-Efficient Connectivity Planning of Inter-Satellite Links for LEO Satellite Constellations
Low Earth Orbit (LEO) satellite constellation is critical to the future development of 6G networks. However, the performance of satellite communication in LEO constellations is challenged by the high-speed of satellite motion and limited on-board ...
Coverage-Aware Cooperative Caching and Efficient Content Distribution Schemes in LEO Satellite Networks
Satellite networks provide the required content to users, specifically those in distant areas, by taking advantage of the wide coverage and low transmission latency of low earth orbit (LEO) constellations. With the improvement of storage and computing ...
