摘要
受现代社会选举制度启发,提出了一种新的节点免疫策略,提出的选举免疫策略按节点得票数量多少选择节点并免疫。基于消息传递方法,给出了大规模配置模型网络上SIR传染病模型的选举免疫策略的数学解析,并比较了选举免疫、随机免疫、目标免疫和熟人免疫策略的效果。数学解析结果和仿真结果表明,选举免疫能够有效控制疾病在无标度网络上的传播。
Inspired by modern voting systems, this paper proposed an effective immunization strategy, which called for the im- munization of nodes in decreasing order of their votes. This paper studied the voting immunization strategy with respect to the susceptible-infected-removed epidemic model, and got an exact mathematical analysis on configuration model networks in the large size limit. It also compared the voting immunization strategy with random immunization, targeted immunization and ac- quaintance immunization. Experiment results show that the voting immunization strategy is very efficient in scale-free net- works,
