摘要
空间信息网络是全球范围的研究热点,我国信息网络科学发展的前沿.组成空间信息网络的空间节点具有高动态运动,网络时空行为复杂的特点,是一个具有高度不确定性,难于建立准确模型的复杂非线性系统.文章分析了目前空间信息网络组网研究的现状,提出以空间信息网络中的浮空平台网络部分为核心,将力学中的受力分析方法引入到大空间尺度下的网络构型中,并将各种影响因素转化为物理学中的力,设计了一种能够应对外部不确定性因素影响的空间信息网络引力模型,获得了一种解决空间信息网络组网问题的可行途径.
Spatial information network become a worldwide research focus in these years, and it is also edge technology in China. Nodes in the spatial information net-work have characteristics of high dynamic and complex behavior in time and space.It is a highly uncertainty and complex nonlinear system and difficult to establish accurate model. In this paper, the current research situation of spatial information net-work is analyzed. The floating platform network is proposed to be the core, reference the gravitation, introduce it to the configuration of large scales spatial information network, and transform the various influence factors to the forces. Design a spatial information gravitation model which can deal with external uncertainty factors influence. Obtain a feasible way to solve the networking problem of spatial information network.
