基于无尺度网络的Internet赋权演化模型研究

Internet是大规模异构性动态性发展的、非集中性的网络。从路由层来描述整个Internet网络,可将这个网络抽象为以成千上万个路由器为节点以及以节点之间的数百万条通信链路为边的无尺度网络。在无尺度网络建模的基础上,综合考虑节点和边的增加、删除和补偿,给出了一个改进的Internet赋权演化模型BBV+,利用连续介质理论对BBV+模型进行理论分析,该模型的点强度和度分布都符合无尺度网络的幂率特征。

RESEARCH ON SCALE-FREE NETWORK BASED INTERNET WEIGHTED EVOLVING MODEL

Internet is a large scale,heterogeneous,dynamically developing and non-centralized network.From the route layer,the entire Internet network is abstracted as a scale-free network which is composed of thousands of routers as nodes with millions of communication links among them as edges.Based on the modeling of scale-free networks,comprehensively considering the increase,deletion and compensation of nodes and edges,a modification of the Internet weighted evolving model,BBV+,is presented.Theoretical analysis b...
