具有通信约束的无标度网络中信息的传播与局部化

Spreading and localization of information in scale-free networks with communication constraints

Kosmas Kosmidis, Armin Bunde

摘要:

我们研究了无标度网络上的信息本地化与通信约束时,由于某种原因,信息只能在“相互信任的节点”(MTN)之间传播。我们提出了一个算法来构建MTN网络,并表明,有一个临界值的可信节点低于信息本地化。如果一小部分p个节点根本不传输信息,则该临界值急剧增加。我们研究了初始信使的分数需要通知所需的分数的网络作为可信节点的平均数量的函数,并讨论了可能的应用模型的营销,风险信息的传播和传播的疾病与非常短的潜伏期。

英文摘要:

We study localization of information on scale free networks with communication constraints when, for some reason, information can propagate only between ``mutually trusted nodes'' (MTN). We propose an algorithm to construct the MTN network and show that there is a critical value of trusted nodes below which information localizes. This critical value increases drastically if a fraction p of nodes does not transfer information at all. We study the fraction of initial messangers needed to inform a desired fraction of the network as a function of the average number of trusted nodes and discuss possible applications of the model to marketing, to the spreading of risky information and to the spreading of a disease with very short incubation time.
