摘要
从信息融合系统的性能指标与网络动力学参数的结合为切入点,分析了信息融合系统的无尺度特性,采用复杂网络中的无尺度BA模型作为信息融合系统的基本拓扑模型.结合信息融合系统的特殊要求对BA模型生成算法中的增长性和择优连接性均做了相应的改进,给出一种信息融合系统改进型BA模型的生成算法.仿真验证表明,改进型BA模型更符合信息融合的网络动力学特征,其平均距离比BA模型改善10%,聚簇系数也有一定程度的改善,并带来整个系统抗毁性能的提升.
The performance indicators of information fusion system and network dynamics parameter are combined in order to analyze the scale - free characteristics of information fusion system. As a result, the scale - free BA model is used to be the topology model of information fusion system. According to the special requirements of information fusion system, the corresponding improvements to the growth and preferential attachment arithmetic are made based on the BA model. An advocated model is given to be the improved BA model of information fusion system. The average length is deceased by 10% in the improved model, and clustering grows larger. The improved BA model is more suitable considering the dynamic characteristics of information fusion system.
