A MAC protocol for communication in distributed constellation self-organizing network

The distributed constellation self-organizing network is a new area in the development of space technology, which is the powerful weapon to win the future information warfare. Communication of information and resources sharing are very important for constellation internal network. This paper analyses the architecture of the satellite constellation. We come up with a new MAC protocol of distributed cluster communication that based on Master-slave mode conversion with a consideration of the satellites´ large amount of number together with its flexible structure and delayed communicative time. Firstly, as the operation control center of the whole network, the master is chosen according to the survival time of the satellite link and the slavers communicate with the master. Secondly, the analysis of access mechanism, the stability of the new protocol and design of the frame format are present.
