在BBV加权网络,WANG加权网络,新加权网络的模型上提出了基于邻居感染权重的微观传播机制并对病毒传播行为进行了仿真分析。研究发现当网络规模和节点的平均度、平均强度相同的情况下,节点的强度分布越分散,爆发速度越快,但达到全局感染的速度越慢;新感染节点的强度分布在不同时间段都服从幂指数规律,以及幂指数r随时间而改变的各种奇特和有意义的现象。 Based on the model of BBV weighted network, WANG weighted network and new weighted network, a micro-propagation mechanism based on neighbor infection weights is proposed and the virus propagation behavior is simulated and analyzed. The results showed that when the network size and node average and average intensity are the same, the intensity distribution of nodes is more dispersed and the burst speed is faster, but the slower the global infection, the intensity distribution of newly infected nodes is different at different time periods Subject to the law of power exponents, and the peculiar and meaningful phenomena that power exponent r changes over time.
