Modeling and Simulation of Space Self-organizing Network based on OPNET

摘要

A scheme of space self-organizing network based on TDMA (Time Division Multiple Access) is proposed for cooperative requirement in cluster flying micro-nano satellites. Network level, node level and process level models are created based on OPNET. Simulation experiments such as nodes autonomous networking, nodes autonomous joining, nodes autonomous exiting and network reorganizing are carried out and the key indexes such as networking time are tested. The scheme has been used in the cluster flying TianTuo-3 satellites developed by National Defense University of Science and Technology and on-orbit networking tests have been successfully carried out. This paper can provide a reference for the design and simulation of space self-organizing network.
