In the name of ALLAH, the most Gracious, the most Merciful Mathematical Proof Reveals How to Make the Internet More Earthquake-Proof Technology Review (03/03/14) Integral geometry can be used to make the spatial layout of the Internet more resistant to damage from an earthquake, according to Hiroshi Saito at NTTs Network Technology Laboratories. Saitos process involves first envisioning a network containing a finite area in which a disaster occurs, and the nodes within this area then have a certain probability of failing. The challenge is optimizing the nodes organization to minimize the probability they will cross a disaster area, should one happen. One rule of thumb yielded from this approach is routes that form shorter zigzags reduce the probability a network intersects a disaster area. A second rule is if the network forms a ring, then additional routes within the ring cannot lower the likelihood that all the routes between a pair of nodes intersect the disaster area. Saito tested the ideas with intensity data from real earthquakes in Japan, superimposing various networks on the data to see how they would fare. The results showed the theoretical rules of thumb should function just as well in the real world as they do in theory. Engineers design networks with protection from damage in mind and then relatively easy restoration should they become damaged, but Saitos approach is to try to miss the disaster completely, if possible. technologyreview/view/525326/mathematical-proof-reveals-how-to-make-the-internet-more-earthquake-proof/
