Research on modeling method of dynamic satellite communication network based on time cumulative Graph Model

Abstract:
Due to the large spatio-temporal scale and high dynamic characteristics of satellite communication network, the traditional time window model and the traditional method of simulating dynamic network processing composed of information accumulation in the time period can not meet the needs of satellite network research under high dynamic conditions. Therefore, the dynamic network modeling method of cumulative graph model is proposed, and the related concepts and indicators under static network are extended to put forward the concept and indicators of dynamic network. Simulation analysis is carried out in small-scale quantitative satellite and large-scale quantitative satellite simulation environment to verify the rationality of the proposed model and realize the unveiling of hidden network characteristics under high dynamic network. Simulation results verify the effectiveness of the proposed method.
