Abstract: | We study the attack vulnerability of network with duplication-divergence
mechanism. Numerical results have shown
that the duplication-divergence network with larger retention probability
σ is more robust against target attack relatively. Furthermore,
duplication-divergence network is broken down more quickly than its counterpart BA network under target attack. Such result is consistent
with the fact of WWW and Internet networks under target attack. So
duplication-divergence model is a more realistic one for us to investigate the
characteristics of the world wide web in future. We also observe that the exponent γ of degree distribution and
average degree are important parameters of networks, reflecting the
performance of networks under target attack. Our results are helpful to the research on the security of network. |
