Performance Evaluation Indicators of Space Dynamic Networks under Broadcast Mechanism

Large-scale heterogeneous constellations will be the major forms of future space-based systems, and the implementation of numerous derived applications depends mainly on intersatellite communication. The nodes representing heterogeneous satellites will form the networks with rapidly changing topolog...
