结合空间信息网络体系架构设计需求,提出了一种具有强抗毁性的空间信息网络结构设计方法.分析并选择自然连通度作为网络的抗毁性测度,提出了一种基于自然连通度的空间信息网络结构优化模型,设计了一种具有免疫审查的人工免疫算法并进行模型求解.仿真实验表明,在链路失效模式和节点失效模式下,优化设计的空间网络与典型空间信息系统相比具有更好的网络结构抗毁性与顽健性.
Combined with the space information network architecture design requirements, a novel optimization designtechnology was proposed, which could achieve strongly network structure invulnerability. The natural connectivity wasanalyzed and selected as the invulnerability measure. In addition, a modified artificial immune algorithm was proposedbased on the natural connectivity and the immune review. Results show that the proposed method improves the networkinvulnerability performance and provides a better robustness compared with typical space information systems in linkfailure mode and node failure mode.
