Immunization of networks with community structure
In this study, an efficient method to immunize modular networks (i.e., networks with community structure) is proposed. The immunization of networks aims at fragmenting networks into small parts with a small number of removed nodes. Its applications include prevention of epidemic spreading, intentional attacks on networks, and conservation of ecosystems. Although preferential immunization of hub...
متن کاملGlobal and local targeted immunization in networks with community structure
Immunization plays an important role in the field of epidemic spreading in complex networks. In previous studies, targeted immunization has been proved to be an effective strategy. However, when extended to networks with community structure, it is unknown whether the superior strategy is to vaccinate the nodes who have the most connections in the entire network (global strategy), or those in th...
متن کاملAn Efficient Immunization Strategy for Community Networks
An efficient algorithm that can properly identify the targets to immunize or quarantine for preventing an epidemic in a population without knowing the global structural information is of obvious importance. Typically, a population is characterized by its community structure and the heterogeneity in the weak ties among nodes bridging over communities. We propose and study an effective algorithm ...
متن کاملOptimal ranking in networks with community structure
The World-Wide Web (WWW) with its enormous size (~ 10 webpages) presents a challenge for efficient information retrieval and ranking. By effectively utilizing the topological information to rank the webpages, Google became the most popular tool on the web. One important feature of the WWW is that it exhibits a strong community structure in which groups of webpages (e.g. those devoted to a commo...
متن کاملCentrality Measures for Networks with Community Structure
Understanding the network structure, and finding out the influential nodes is a challenging issue in the large networks. Identifying the most influential nodes in the network can be useful in many applications like immunization of nodes in case of epidemic spreading, during intentional attacks on complex networks. A lot of research is done to devise centrality measures which could efficiently i...
