加权BA网络负荷重分配建模及级联抗毁性
A Load Reallocation Model for Weighted Scale-Free Network and Cascading Invulnerability Research
摘要
Abstract
On consideration of the difference between edges in the network,this paper constructs a weighted scale-free network model based on the BA scale-free network model,builds a load reallocation strategy model analyzes the efforts of local distribution size of network on survivability determines the optimal load reallocation strategy,and analyzes the influence of network parameters on the network invulnerability under deliberate attack condition and different load reallocation strategies.The simulation results show that the smaller the network weight coefficient and the greater the average degree,the stronger the network survivability,namely the network''s cascading invulnerability becomes stronger while the network is more homogenous and denser and the network''s invulnerability is always superior to the handy full load reallocation when the handy local load reallocation strategy is adopted.This research can provide a theoretical reference for improving the network invulnerability.关键词
