Information propagation on modular networks. Physical review. E, Statistical, nonlinear, and soft matter physics [Phys Rev E Stat Nonlin Soft Matter Phys] Journal article | | Title | Information propagation on modular networks. | | Author(s) | Huang L, Park K, Lai YC | | Institution | Department of Electrical Engineering, Arizona State University, Tempe, AZ 85287, USA. | | Source | Phys Rev E Stat Nonlin Soft Matter Phys 2006 Mar; 73(3 Pt 2):035103. | | Abstract | Networks with a community (or modular) structure underlie many social and biological phenomena. In such a network individuals tend to form sparsely linked local communities, each having dense internal connections. We investigate the dynamics of information propagation on modular networks by using a three-state epidemic model with a unit spreading rate (i.e., the probability for a susceptible individual to be "infected" with the information is one). We find a surprising, resonancelike phenomenon: the information lifetime on the network can be maximized by the number of modules. The result can be useful for optimizing or controlling information spread on social or biological networks. | | Language | eng | | Pub Type(s) | Journal Article
