基于实际短信网络的统计特征,提出了一种短信网络的加权演化模型,并在此模型上研究了谣言传播行为.考虑到边权是认可概率的关键影响因子,故改进了现有的谣言传播模型;通过改变边权弥散程度和网络结构参数,重点研究和分析了边权分布及聚类系数对谣言短信传播行为的影响.仿真实验表明:边权弥散程度越高,对谣言传播的抑制效果越好;聚类系数越高,谣言反而容易扩散蔓延.
By analyzing some statistical features of real short message networks(SMNs),a weighted evolutionary model(WEM) is proposed,based on which the rumor spreading behavior is studied as well.An improved rumor spreading model is then introduced,which takes the weight as a key factor of approving probability.Moreover,by changing weight dispersion and parameters of network structure,this paper focuses on studying the impact of weight distribution and cluster coefficient on rumor spreading.Simulation results show that a network with larger weight dispersion results in good resistance to rumor spreading,while a greater cluster coefficient is conducive to rumor spreading.
