Colors are assigned according to the coreness: vertices with coreness 1 are violet, and the maximum coreness vertices are red, following the rainbow color scale. The node degree scale is also displayed, showing the maximum degree of the network.









<< Previous Next >> Internet routers CAIDA IR_CAIDA is a router level map of Internet network. Each node represents a router and each edge is a link between two routers. The data corresponds to an exploration done at CAIDA organization. Colors are assigned according to the coreness: vertices with coreness 1 are violet, and the maximum coreness vertices are red, following the rainbow color scale.

<< Previous Next >> Barabasi Albert BA corresponds to the Barabási-Albert model. considers growing networks according to the preferential attachment mechanism: each new node is connected to m already existing nodes chosen with a probability proportional to their starting degree. This network has 10000 nodes and m=2. Colors are assigned according to the coreness: vertices with coreness 1 are violet, and the maximum coreness vertices are red, following the rainbow color scale. The node degree scale is also displayed, showing the maximum degree of the network.









<< Previous Next >> Barabasi Albert RND RBA corresponds to the Barab´si-Albert model. considers growing networks according to the preferential attachment mechanism: each new node is connected to m already existing nodes chosen with a probability proportional to their starting degree. This network has 1000 nodes and varying m randomly between 1 and 10 (at each time step). Colors are assigned according to the coreness: vertices with coreness 1 are violet, and the maximum coreness vertices are red, following the rainbow color scale. The node degree scale is also displayed, showing the maximum degree of the network.









<< Previous Next >> Extended FKP Extended_FKP is an extension of the work of Fabrikant, Koutsoupias and Papadimitriou, Heuristically Optimized Trade-Offs: A New Paradigm for Power Laws in the Internet model. This model of a growing network embedded in a two-dimensional space is essentially based on a competition between distances in the Euclidean space and on the graph: a new node is connected to already existing nodes in a way to optimize a combination of its distance on the graph to a predefined "center" and the Euclidean length of the connections. We consider a network constructed along the lines of Alvarez-Hamelin and Scahbanel 2004, which has a scale-free distribution of connectivities P(k)~k^(-a) with exponent a=2.4. Colors are assigned according to the coreness: vertices with coreness 1 are violet, and the maximum coreness vertices are red, following the rainbow color scale. The node degree scale is also displayed, showing the maximum degree of the network.
