Model Establishment of Rumor Spreading in Social Network Based on Synthesis Immunization Strategy

An improved synthesis immunization strategy was proposed through analyzing and comparing advantages and disadvantages of various immunization strategies. This immunization strategy amalgamated the importance of node degree into the classic synthesis immunization strategy. Based on the ideal social network, the improved synthesis immunization strategy was used into the SEIR model(epidemic dynamics models with latency) and also was utilized to do the simulation for the evolution process of rumor spreading before and after immunization. Computer simulation results show that the improved synthesis immunization strategy has better immune effect on rumor spreading in the social network.
