基于随机游走的蠕虫网络演化研究

Research on Worm Network Evolution Based on Random Walkers

鉴于无标度网络的健壮性和小世界特性是蠕虫网络的理想特征,借助于复杂网络理论,提出了一个基于随机游走的蠕虫网络演化模型。该模型依据主机性能和网络的带宽采取择优的方式从蠕虫网络中选择合适的节点与新感染的主机建立连接。理论分析和模拟实验表明:所建立蠕虫网络具有无标度网络的性质。

Robustness and small-world property of scale-free network are the desirable features in worm network., a worm evolution model is proposed based on random walkers by the complex network theory. According to host capability and network bandwidth, the model builds a valid connection between a new infected host and the suitable nodes selected from worm network using preferential attachment. Theoretical analysis and simulation experiments show that such network exhibits a power-law distribution of node degree.
