Enhancing robustness and immunization in geographical networks.
We find that different geographical structures of networks lead to varied percolation thresholds, although these networks may have similar abstract topological structures. Thus, strategies for enhancing robustness and immunization of a geographical network are proposed. Using the generating function formalism, we obtain an explicit form of the percolation threshold qc for networks containing arbitrary order cycles. For three-cycles, the dependence of qc on the clustering coefficients is ascertained. The analysis substantiates the validity of the strategies with analytical evidence.
