| With the development of mobile Internet, the dissemination of crisis information demonstrated more widely and more rapidly, beyond time and space, and more interactive and other characters. This Article has done research of mechanism of crisis information dissemination with theory and practice in network topology and dissemination model. Specifically, Including the following two aspects of content and research results:First, do topology modeling and analysis on the mobile Internet crisis communication network. Statistical analysis of the behavioral characteristics of mobile Internet users by questionnaire survey, based on these characteristics, develop a network topology model of the evolution mechanism and the model assumes conditions. Then based on the original BA model of scale-free networks, built mobile Internet-based crisis information dissemination network topology model, by MATLAB simulation, mobile Internet information transmission network has the characteristics and scale-free small-world characteristics, and we found that the model can reflect the actual situation of information dissemination network.Second, based on network topology modeling, established a reasonable mobile Internet model of interpersonal crisis information communication. This article based on the established network topology model derived topological properties of the mobile Internet, analysis the crisis information dissemination of the evolution of rules and process description, established information dissemination model the establishment of the information dissemination model, the simulation model proves that is consistent with the actual data, interpersonal communication of information to carry out a similar quantitative study provides valuable reference ideas for similar follow-up quantitative studies.The research results of crisis communication network topology modeling and communication model not only has theoretical value but also the practical value, can provide a useful reference for follow-up study. |
