    Neighbor satellite load based low orbit satellite distributed routing algorithm by Mingchuan YANG, Guanchang XUE, Qingyi LI

    Published 2021-08-01
    “…Satellites are highly flexible and maneuverable, and they are not easily affected by ground factors, which has led to the rapid development of space satellite technology.Satellite networks always have load congestion problem as the load increases, making routing algorithms a core issue in the field of satellite network research.Based on the problems of congestion mitigation, signaling overhead, and algorithm complexity, the distributed routing algorithm for local load balancing of LEO (low earth orbit) satellite networks was deeply studied.The network model was constructed based on the Iridium satellite system and a distributed routing algorithm based on the load status of neighbor satellite (DRNL) was proposed, which included such as load status update of neighbor nodes, load balancing and routing decision.It had a certain degree of portability and could adapt to other polar or near polar orbit constellation.The simulation results based on the OPNET show that the DRNL can better adapt to the heavier network loads state, alleviate satellite congestion, obtain lower delay and packet loss.…”

    Remote Satellites Computing transmission and Key Technologies by lang HuYan, Ying Li, Quan Zhou, Jiayuan Wei, Juanni Liu, Yi Zhang

    Published 2022-06-01
    “…The diversity of remote sensing data and the increase of acquisition ability make the amount of data generated on the satellite increase geometrically.This situation puts tremendous pressure on the remote satellite data transmission system.This makes the remote satellite data transmission system unable to meet the needs of real-time transmission and becomes the bottleneck of remote sensing data application.The research on massive remote satellite data transmission systems and technology is one of the frontier fi elds of international satellite information network science and technology.Focused on the critical problems of remote satellite real-time data transmission bottleneck, remote sensing data transmission timeliness, remote sensing load utilization, and onboard storage, combined with the traditional satellite data transmission system with onboard intelligent processing, a new remote satellite computing transmission framework was proposed, and its key technologies were analyzed.…”
