abstract = {To address the issues of satellite networks in integrated space-air-ground networks being susceptible to Single Event Effect (SEE), which can lead to link disruptions and service degradation, SEE oriented resilient networking and reconfiguration methods for satellite networks are investigated. The aim is to enhance the survivability and service reliability of satellite networks under SEE. A collaborative resilient architecture comprising three layers of space-based, air-based, and ground-based networks is proposed, along with a resilient resource pool that includes a backup resource pool and a backup node pool. A risk awareness module is integrated to enable the satellite network to detect faulty nodes at an early stage. Based on the Walker network architecture and time slice mechanism, a routing planning algorithm with the minimum delay and risk is proposed by incorporating the path SEE failure rate and link delay as weights into the Dijkstra algorithm. Meanwhile, faults caused by SEE are classified into two levels: Level 1 reversible faults induced by Single Event Upset (SEU) and Level 2 irreversible faults caused by Single Event Burnouts (SEB). A fault detection mechanism combining local detection, neighbor verification, and ground confirmation is established. Additionally, a local route repair algorithm and a node collaborative replacement repair algorithm are proposed, forming a hierarchical elastic reconfiguration system. STK and NS3 joint simulations based on the Iridium constellation show that the time overhead for detecting and reconfiguring faulty nodes is within the acceptable range of the system. After faulty nodes appear in the network, the proposed method can reconfigure the network in a timely manner, and the packet delivery rate for Level 1 and Level 2 fault nodes has been increased to 97.359% and 96.457%, respectively. The research results provide key technical support for the stable operation of satellite networks in high-radiation environments.}
