| 摘 要： | 基于一维元胞自动机,考虑信息网络节点全局交互和网络通信流量不均衡的特点,提出新的susceptible -infected - susceptible (SIS)病毒传播模型,研究多种网络拓扑结构下病毒传播行为.研究表明,随着网络通信流量增大,病毒在不同拓扑结构网络中传播速度都明显加快,并在更短的时间内达到稳定的更高的感染规模.研究还发现,在考虑一定通信流量和路由协议下,病毒在节点度分布异质化程度较高的网络中最不易爆发.

| Abstract: | Based on the one-dimensional cellular automata and considering the features of the global interaction of information network’s nodes and the unbalances of communication flows,a new susceptible-infected-susceptible(SIS) model is proposed to study epidemic spreading in a variety of network topologies with communication flow.Simulation results show that the propagation velocity increases obviously and the infection rate will reach a stable and higher scale in a short time in different network topologies with the communication flow becoming large.Moreover,in a certain communication flow state and under a certain routing protocol,the outbreak of epidemics is very impossible in the networks with higher heterogeneity of degree distribution. |
