Duo to its characteristics such as high dynamic topology, sparse distribution of nodes, frequent link interruption and terminator node random motion,a routing algorithm resolving terminator node random motion is proposed.To solve the routing problem of the random motion,the algorithm utilizes probability calculation and store?and?forward mechanism. In accordance with the intermittent connectivity phases of the routes and the information on node encounter probabilities,the available path is identified.Theoretical analysis and simulation results show that SRM achieves good performance and is suitable for spatial satellite network application.
