摘要:
由于空间信息网络的空间和时间的大尺度特性及其复杂度的大幅提高,已有的信息传输能力衡量方法已无法有效地衡量现有和未来的空间信息网络.本研究首先建立复杂的空间信息网络模型,通过分析空间信息网络的数据接入能力和网内数据传输能力,来衡量整个空间信息网络的通信业务承载能力.最后利用STK和Matlab仿真软件,进行协同仿真,验证了所提出的衡量方法的合理性.

Abstract:
Because of the large scale characteristic of space information network in terms of space and time and the increasing of its complexity,existing measuring methods of information transmission capacity have been unable to measure the existing and future space information networkeffectively.In this study,we firstly established a complex model of space information network,and measured the whole space information network capacity by means of analyzing data access capability to the network and data transmission capability within the network.At last,we verified the rationality of the proposed measuring method by using STK and Matlab simulation software for collaborative simulation.
