Abstract: Combining visit rate of the node itself and network structure,an improved scale-free network epidemic model and a new network distribution algorithm are proposed.Compared with prior algorithms,simulation experiments confirm the effectiveness and efficiency of our algorithm.

Key words: virus epidemic models, network immunization, target node, key value

摘要: 结合传统的网络拓扑结构和单机节点访问率,改进了无标度网络结构下病毒传播模型,进而提出了新的目标节点的定义。根据新的网络病毒传播模型,提出了一种基于门限判决的计算机病毒免疫算法。利用OPENET仿真实验平台,比较了该算法与以往免疫算法的性能和效率。仿真结果表明该算法免疫更少的节点即可达到全网免疫状态,且时间更快,效率更高。因此,该文算法能有效遏制病毒大规模爆发和传播,具有一定的社会意义和经济价值。
