Study on Complex Network Stability Based on the Structure Parameters

According to several attributes of network structure, firstly, we give a summary about some related works of network stability. And then, through the simulation experiments, we explored the influence of network density and network size on the stability of complex networks and got some interesting conclusions. Finally, we defined a factor η for the connection strength of community, and we speculate that there is a threshold η_c, it led to the network stability decreased and then increased with the increase of η, and eventually reached a peak.
