title: Enhancing robustness and immunization in geographical networks.
abstract: 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.
