改进免疫战略

Improving immunization strategies

摘要:

我们引入了一种免疫方法,其中免疫所需的疫苗接种的百分比接近最高度节点的有针对性的免疫方案的最优值。我们的策略保留了纯粹本地的优势,而不需要对全球网络结构或识别的最高程度的节点的知识。该方法包括选择一个随机节点,并要求邻居有更多的链接比自己或超过一个给定的阈值,并免疫他。我们比较这种方法与其他有效的策略在三个真实的社交网络和无标度网络模型,并发现它是显着更有效。

英文摘要:

We introduce an immunization method where the percentage of required vaccinations for immunity are close to the optimal value of a targeted immunization scheme of highest degree nodes. Our strategy retains the advantage of being purely local, without the need of knowledge on the global network structure or identification of the highest degree nodes. The method consists of selecting a random node and asking for a neighbor that has more links than himself or more than a given threshold and immunizing him. We compare this method to other efficient strategies on three real social networks and on a scale-free network model, and find it to be significantly more effective.
