子网络的连接模式对关联网络可靠性影响研究

ON IMPACT OF SUB-NETWORKS CONNECTION PATTERN ON THE RELIABILITY OF INTERDEPENDENT NETWORKS

为了分析关联网络中子网络之间连接方式对网络可靠性的影响,根据不同子网络之间连接的度相关性,建立关联网络中子网络之间的连接模型,以节点之间非交叉路径的最大条数为可靠性测度,对由4个子网络组成的网络系统进行了分析。结果表明,当子网络之间的连接具有异配性时,网络具有较高的可靠性,但过大的异配性反而会降低网络的可靠性。

To investigate the impact of the connection pattern of sub-networks in interdependent networks on the reliability of networks,the connection models between sub-networks in interdependent networks are established according to the degree correlation of the connection between different sub-networks.The maximum number of disjoint paths between nodes is used as the measurement of reliability,and with it the network system comprising of four sub-networks has been analysed.Results show that the network has higher reliability when the connection between sub-networks is disassortative while too high disassortative may in turn reduce the network reliability.
