摘要
将经典的SI(Susceptible-Infected)模型集成到闪烁小世界网络中,分析疾病传播的动态行为。大量的数值仿真表明,长程连接的动态切换能够显著加快感染传播的动态过程,并且切换频率越高,疾病传播也越快。研究结果对于深入理解传染病的传播规律,预防和控制流行病早期在真实复杂网络中的传播具有重要的现实意义。
In this paper,we integrate the classical SI（Susceptible-Infected） epidemic model into the blinking small world networks to analyze the dynamical behavior of disease spreading.Large scale numerical simulations indicate that the frequent switching of long range connections can obviously accelerate the dynamical spreading processes,and the higher the connection switches,the faster the disease spreads.It is great significance of the current results to deeply understand the spreading behavior of infectious diseases,to prevent and control the early outbreaks of epidemics within real complex networks.
