基于元胞自動機的手機信息傳播模型研究
[Abstract]:With the progress of the information age and the development of the Internet and communication technology, the mobile phone information service, as a new means of communication, is cheap, convenient to receive and receive, and not subject to space-time constraints. Has become a more important means of communication and popular with mobile phone users. The understanding of mobile phone information dissemination is only micro level, mobile phone information users can not understand the dissemination of information macroscopically. In order to establish the model of mobile phone information transmission, the cellular automata, the modeling tool of complex system, is adopted. Cellular automata (CA) is a spatial discrete, time-discrete and state-discrete model composed of a large number of simple, locally interacting cells. The transmission of mobile phone information is not restricted by time and space, which accords with the characteristics of cellular automata. Therefore, the cellular automata model of mobile phone information transmission is established from qualitative and quantitative aspects. Firstly, this paper briefly introduces the theory of cellular automata, which provides a theoretical basis for the establishment of cellular automata model of mobile phone information. Then there is the collection and analysis of data. First of all, according to the content of mobile phone information, the mobile phone information is divided into ten categories: blessing, greeting, entertainment, news, jokes, chat, advertising, notification, advocacy (such as text messages boycotting Carrefour). Reminders (such as the Guangyuan citrus event in Sichuan). The purpose of this paper is to study the models of mobile phone information transmission, and to simulate the process and scope of its spread. Then according to the characteristics of the subjects, the eight neighbor elements of the cellular automata are set as: parents, brothers and sisters, relatives, friends, classmates, colleagues, teachers and other eight categories. Then the questionnaire is designed to obtain the data of mobile phone information using online survey. The most important thing is to obtain the probability that the cell can transmit the mobile phone information to the eight neighboring elements around. Finally, using this probability to establish cellular automata model, simulate the process of various mobile phone information transmission. In addition, the characteristics of the model and the reasons for the result are analyzed.
