Random geometric graphs have been one of the fundamental models for reasoning about wireless networks: one places n points at random in a region of the plane (typically a square o...

A geometric graph is a simple graph G = (V, E) with an embedding of the set V in the plane such that the points that represent V are in general position. A geometric graph is said...
Abstract: A triangulated network of mobile units is modelled by means of a graph transformation system in which graph nodes are labelled with geometric coordinates and edges are la...
—Wormhole attack is a severe threat to wireless ad hoc and sensor networks. Most existing countermeasures either require specialized hardware devices or make strong assumptions o...

Abstract—Intuitively, identification of nodes close to the network edge is key to the successful setup, and continued operation, of many sensor network protocols and application...
