Impact of Community Structure on Network Efficiency and Communicability

摘要

To explore the impact of community structure on some measures of about the capability of information transfer and transformation occurring on such topologies, we set up a kind of network model with community structure which shows obvious local and global small world characteristics. Under the control of the parameters of the network generation, the networks with the different level on cohesive intension of community and rewire randomization can be got. Then we compare the global efficiency and network communicability relative to the different values of control parameters. We show that transport is more difficult with the more pronounced community structure.
