基于局域择优的作战信息网络模型

Model of Combat Information Network Based on Local Preferential Attachment

针对目前战术通信网络模型存在缺乏宏观可调参数以及度分布不便于解析的特点,将作战信息网络划分为核心层、中间层和用户层,提出了作战信息网络的演化网络模型,并对带可调参数的演化网络模型进行了度分布平均场解析.从理论上阐明了作战信息网络的幂率介于2~4,证明了单位时间内平均到达节点数对幂率没有影响.对特征参数进行了仿真,说明了在不同择优概率情况下平均路径长度和集群系数具有不同的分布规律.

For lack of macro-control parameters and convenient solution of tactical communication network,by classifying combat information network into three hierarchies which are core hierarchy,middle hierarchy and user hierarchy,an evolving network model of combat information network has been proposed.The degree distribution of evolving network with adjusting parameter is solved based on mean-field theory.Clarifying the power law of combat information network is between 2and 4on theory,demonstrating the number of arriving node on average in a unit time has no effect on power law.Simulating the characteristic parameters,the distribution of average path length and clustering coefficient under different preferential attachment probability presents different principles.
