In all networks, like road or airline traffic networks, the Internet, cancer tumors or industry supply chains, you need to pass packets from node to node, such as cars, information or data. But which are the most efficient, decentralized networks or hub-like centralized ones?
According to Technology Research News (TRN), researchers from Oxford University, U.K., have designed a model which maps traffic congestion. This model combines roads going through the center of a city and other ones avoiding it (full article)
And they found that, from a cost point of view, it would be sometimes better to close roads going through cities than adding more. They also think that these conclusions can be applied to almost all kinds of networks, biological ones or created by humans. This overview contains more details, references and illustrations about this network model.
