2. Regular structures in ad-hoc networks • Ad-hoc network are networks that are created between mobile nodes – nodes just communicate to its immediate neighbors • Dynamic, unreliable, potentially short-lived • Unpredictable in movement • Ad-hoc networks created by cars (car-to-car networking) have node-movement restrictions – due to roads • Still difficult to create efficient algorithms for ad-hoc networks • Regular structures (N2R, cordal rings, ...) are used in fixed networks (e.g. fiber) and have efficient algorithms (broadcasting, routing, fault-tolerance...) • Project: • Use node placement and movement knowledge (or estimates of it) to create regular structures for ad-hoc network • With mobility • Without mobility
