In view of the current research methods for the survivability of spatial information networks,multifunctional hierarchy and dynamic characteristics are not considered simultaneously.Firstly,this paper summarizes the main methods of survivability research and three main attack strategies.Secondly,the idea of supply and demand flow and the method of time accumulation graph are integrated into the spatial information network model,and the multi-layer dynamic spatial network accumulation model is established.Thirdly,the survivability evaluation index of the dynamic network model,time-dependent network connectivity,is proposed to construct the survivability analysis method model of spatial information network.Finally,taking navigation satellite network,communication satellite network and remote sensing satellite network as examples,this paper constructs a simulation idea of space information network,carries out an attack strategy according to the three kinds of attack strategies,and analyzes the survivability of space information network.The experimental results verify the rationality of the proposed method and the effectiveness of the index.
