Research On The Stability Of Multi-source Information Dissemination Network Based On Fixed Point Simulation

The phenomenon of the crowd is common in human society.Taking Internet and mobile communications as the link,human groups,big data,and the Internet of Things have achieved extensive and deep interconnections.Human beings have begun to enter the era of crowd network in which everything is interconnected.The speech on the Internet has the characteristics of cross-space and anonymity,which makes the information spread in an almost free state in the network.The symbiosis and interconnection of many individuals in the crowd network have certain uncertainty and contingencies,and the dissemination state and dissemination path of information are unpredictable.Under the condition of multi-source information dissemination,the correlation structure and behavior among individuals make the intelligent network in a stable and chaotic alternating state.Due to the complex network structure,this paper mainly studies the change process of network stability in the process of condition of alternating dissemination of multi-source information and verifies by building a simulation platform.This paper is based on the National Key R & D Program topic – research and development of crowd network theory simulation and experimental platform,the main content of the research includes the following four aspects:This paper defines intelligent vectors(including information vectors and preference vectors)to express,compare and operate intelligence,and then determines the information dissemination behavior of digital-subjects,provides abstract expression and reasoning for the integrated mechanism of multi-source information,and effectively explains the mechanism of irrational members in the process of information dissemination.This paper proposes the fixed point of multi-source information dissemination network—information intensity sum,which is used as the stability characterization of the network system,which is used to intuitively reflect the stability change process of the entire network and provides the basis for the effective supervision for the information communication network.This paper builds a multi-source information dissemination simulation propulsion model based on digital-subjects,which is used to simulate the phenomenon of multi-source information dissemination in the real world,and puts forward the perturbation injection mechanism based on the collective intelligence unit,simulates the information manipulation behavior of the "network pusher",analyzes the influence of the external environment on the stability of the multi-source information dissemination network,and provides an effective means for tracing the source of public opinion.In order to verify the proposed theory,this paper builds a fixed point simulation system,designs a specific simulation example,and proves the information intensity sum can be used as an indicator to verify the stability of the system.
