摘要:
基于复杂网络理论,建立基于多智能体的低轨卫星网络动态抗毁性模型.完成低轨卫星网络的分布式拓扑结构的构建,将每个网络节点看成是一个具有自修复能力的agent,并在不完全信息条件下,采用一般性攻击策略研究信关站的分布、攻击强度、攻击力度、信息指数、自修复能力对低轨卫星网络抗毁性的影响.仿真结果表明:系统存在恢复时滞,对随机打击具有较强的鲁棒性,对蓄意打击脆弱性降低、稳定性提高,自修复性能弱化了网络的无标度特性;信息指数比攻击强度及攻击力度对网络抗毁性的影响更大;信关站分布对空间段网络抗毁性的影响较小,对地面段网络抗毁性影响较大,表明星际链路使得低轨卫星星座对地面网的依赖性大为降低.

Abstract:
Based on the complex network theory, a dynamic invulnerability model of low earth orbit(LEO) satellite network based on multi-agent is established. The distributed topology structure of LEO satellite network is completed, each network node is regarded as a self repairing agent, and under the condition of incomplete information, the general attack strategy is used to study the influence of the gate-station'distribution, attack intensity, attack strength, information index and self repair ability to the survivability of low orbit satellite network. The simulation results show that the system exists recovery lag, it has strong robustness to random strike, and lower vulnerability and better stability for deliberate attack, and self repair performance reduces the network's scale-free characteristics; information index has greater impact on network survivability than attack intensity and attack strength, and the distribution of gate-stations has little effect on network destruction, which shows that the dependence of the low orbit satellite constellations on the ground network is greatly reduced due to the use of interstellar links.
Key words:  LEO satellite network  self repair  incomplete information  invulnerability
