IEEE Network magazine is seeking tutorial and state-of-the-art summaries on the application of network science to the communications sector, including wired, wireless, Internet, financial (FedWire, SWIFT, ATM), and special-purpose systems such as GPS or military networks. Network science is the study of static and dynamic graphs and their application to a variety of engineering and scientific disciplines. Of particular interest are papers on webgraph analysis of networks, exploring centrality measures such as clustering and betweeness, analyzing risk and resilience metrics related to homeland security, studies of emergence properties of real networks such as self-organized criticality, algorithms for navigating peer-peer networks, modeling the spread of viral epidemics, analyzing chaotic behavior, and describing tools and techniques used in the design and analysis of networks.
