基于动态可视化的空间信息网络拓扑演化浅析

Topology Evolution Analysis of Space Information Networks Based on Dynamic Visualization

随着人类社会和虚拟社会对各类网络依赖程度的增加,网络拓扑演化也逐渐发展成为了研究热点。现阶段,主流研究思想是基于复杂网络理论而展开,致使出现演化方法不易移植、演化思路固定单一和演化结果不易理解等。介绍了空间信息网络的概念及其体系结构,分析了网络拓扑演化的现状和不足,论述了动态可视化的基本原理,从而探索性地提出了一种基于动态可视化的网络拓扑演化方法,简称为可视演化方法。从网络布局、网络属性可视化和用户交互三方面阐述了实现可视演化方法的关键技术,从关联性和优劣性两个角度完成了可视演化方法实现的可行性论证。引入可视化的相关技术与原理研究空间信息网络拓扑动态演化,其演化结果不仅直观形象、易于理解,同时还具有较强的普及性,因此,可视演化方法对于研究空间信息网络拓扑演化具有重要的意义。

With the increase of dependence of human and virtual society on networks,the topology evolution of networks has gradually developed into a hot-topic issue.At present,the mainstream research thought is expanded based on the complex network theory,and it makes the evolution method not easy to transplant,the evolution idea fixed single and the evolution result is not easy to understand,and so on. We introduce the concept and architecture of the Space Information Network (SIN),and analyze the present situation of network topology evolution.We discuss the basic principle of dynamic visualization, and propose a topology evolution method of SIN based on dynamic visualization,abbreviated as visual e- volution method.We expound the key technology of realizing the visual evolution method from three aspects of network layout,network attribute visualization and user interaction,and complete the feasibility demonstration of the realization of visual evolution method from two angles of relevance and pros and cons.The related technology and principle of visualization are introduced to study the topology dynamic evolution of SIN,and its evolution result is not only intuitive image,easy to understand,but also has strong popularity.Consequently,the visual evolution method is of great significance for the study of topology evolution of SIN.
