Abstract:
Based on the research of mathematic model, a single-and-multi-layer model is established, on which a new multilayered routing algorithm for space information network is proposed. Results of analysis and simulation show that the algorithm has little delay and reduces the handover probability of path, which effectively improves the routing performance of the space information network.
