A Hierarchy Management Framework for LEO Satellite Communication Networks

An autonomous iteration-based approach is proposed to identify faulty links for LEO satellite systems employing intersatellite links (ISLpsilas). A designed network satellite with management responsibilities collects the routing information of communication itself with other satellites, based on which a fault diagnosis model is introduced. Then the most likely faulty link is identified by using an iteration-based probability method, in conjunction with which an autonomuos localization procedure is described to pinpoint the actual faulty links. Based on this approach, a hierarchy network management architecture is designed to deal with the fault diagnosis for LEO satellite networks.The performance of the algorithm is evaluated through simulation.
