一种改进的演化型Internet拓扑模型

A Novel Internet Topology Model Based on Evolution

通过分析传统的基于偏好依附的演化型Internet拓扑模型BA模型,针对其考虑网络演化过程中事件的不完善性,提出一种BA模型的改进VBA模型。该模型更全面地考虑了网络演化过程中加边、加点和去边三种事件。对VBA模型的拓扑度量值分析结果表明,该模型能够生成比传统模型更优的具有幂律度分布和小世界特性的网络实例。

Analyzes a classical growing network model based on preferential attachment, the BA model. An improved BA model is presented which takes into account of adding either nodes or edges and deleting edges in the evolving networks. The analysis of its topology metrics shows that VBA model can generate better graphs with a power-law degree distribution and small - world properties.
