Research on Information Transmission Characteristics of Two-Layer Communication Network

With the development of the Internet, the marketing model of the communications industry has transformed from call-based to social application-based. Analyzing information transmission of social application helps to develop marketing strategy for different customers’ needs. The paper proposes and constructs a two-layer communication user spreading model based on the SIR information dissemination model. Then we analyze the traditional model of virus spread on the network’s application, and get the simulation results of immunization strategy and the communication process of social application information on WeChat, microblog and QQ. Combining with the actual data, simulation results show that the spread of the three types of social applications reaches a peak in a short time with the increase of the spreading rate. The spreading scale of WeChat application is larger than the other two types of applications on the same spread rate. Based on the acquaintance (target) immune strategy, the three types of applications have faster transmission inhibition than the random immune strategy. The research results of this paper provide an effective theoretical base for setting up individuality service combination of mobile communication enterprise.
