Safety Analysis of Network System Based on Small World Topological Model
JI Xiao-heng · Jisuanji gongcheng · 2010
Considering the computer network as an integrated unit,the effect of the system's topological characteristics on the prevalence of virus is analyzed by using the small world network theory,and the rules which can describe the safe sensitivity of the network nodes are proposed.The virus grade diffusion model based on the small world clustering is established and the propagation intensity between the nodes is decided.The virus propagation paths with high risk and corresponding crisp nodes are found with ant colony algorithm,which plays a key role in the network safety prevention.
