Abstract：To solve the communication link break of satellite nodes invalidation by various attacks because of the openness of space communication, a survivability routing protocol of GEOLEO satellite network was designed based on the routing protocols of satellite network and random linear network coding. In view of satellite security management and communication problems, the GEO satellites group was used to manage different groups of LEO satellites when LEO satellites were main communication method. In order to improve the survivability and efficiency of routing, every LEO satellite was maintained with a onestep adjacent table updated with LEO satellite time period. When the original LEO satellites nodes needed routing, the protocol would search for the routing in the onestep adjacent table. If the target LEO satellites nodes were in the onestep adjacent table, the message would be sent through the onestep adjacent table of original LEO satellites. Otherwise, the original LEO satellites would produce a routing table during the searching for RREQ message through random linear network coding routing. The simulation results show that the proposed routing protocol can greatly improve the performance of survivability routing and reduce the times of routing message transmission.
