Research On Rumor Propagation Model Based On Complex Networks

Compared with general rumor propagation,malicious rumor propagation can lead to a larger scope of influence and a faster diffusion velocity.For these features,how to establish a model with effective prevention and control is a worthy of research work.A new rumor propagation model is proposed in complex networks,which divides the spreaders in the malicious propagation phenomenon into malicious spreaders and ordinary spreaders according to the purpose of propagation,and takes into account the hesitators who show a hesitation after hearing the rumor.By analyzing the differences when different people hear rumors,the five states of the model are defined,and the propagation rules of the model are given.The corresponding mathematical model is constructed and the propagation threshold of the model is analyzed.In addition,the random immunization strategy and targeted immunization strategy that can effectively control rumors are used in the model.The simulation results show that the malicious spreaders can make the rumor propagation cycle shorter,and determine the parameters that can influence the rumor propagation cycle.From the effect of the two immunization strategies on the model,the targeted immunization for the malicious spreaders is more effective than the random immunization for the ignorant.
