Study of an Access Protocol for Satellite Network with Open TDMA

The communication architecture of multi-constellation network is investigated, and an inter-satellite network access protocol based on open time division multiple access is proposed. The protocol can realize the smooth access of different constellation nodes to channels through the communication interaction frames, and achieve the interconnection among different constellations. Moreover it can provide various priority QoS guarantees for the nodes in constellations. Then the simulation results verify the rationality of the data transmission architecture and the validity of the protocol, which provides a way for network communication in the large-scale multi-constellations.
