摘要
为了研究免疫有效时间对复杂网络中病毒传播的影响,基于元胞自动机建立复杂网络不完全免疫的病毒传播模型,并分别在最近邻耦合网络、Erdos-Renyi随机网络、Watts-Strogatz小世界网络和Barabasi-Albert无标度网络中进行仿真研究。结果表明:节点免疫有效时间的增大,能够有效地遏制复杂网络病毒传播范围并增大病毒传播阈值。
In order to investigate the effects of immune valid time on virus spreading on complex networks, models of virus spreading with incomplete immunization are proposed based on cellular automata, and the proposed models are run on nearest-neighbor coupled network, Erdos-Renyi random graph network, Watts-Strogatz small world network and Barabasi-Albert power law network respectively. The result of simulations shows that the enhancement of immune valid time can reduce the epidemic prevalence and enhance the epidemic threshold of the above four kinds of networks.
