Vertex labeling and routing in expanded Apollonian networks
We present a family of networks, expanded deterministic Apollonian networks, which are a generalization of the Apollonian networks and are simultaneously scale-free, small-world, and highly clustered. We introduce a labeling of their nodes that allows one to determine a shortest path routing between any two nodes of the network based only on the labels
Models deterministes de xarxes complexes
En estudis recents s'ha observat que moltes xarxes associades a sistemes
complexos pertanyen a una nova categoria que s'ha volgut anomenar petit-món amb
invarià ncia d'escala. Molts dels models que s'han desenvolupat per a la descripció
matemà tica d'aquestes xarxes es basen en construccions probabilÃstiques. Tanmateix,
la consideració de models deterministes és útil per completar i millorar les tècniques
probabilÃstiques i d'altres basades en simulacions. En aquest article introduïm els
conceptes i models bà sics que s'han considerat en l'estudi de xarxes complexes i es
presenten diversos models deterministes que es generen a partir de grafs complets.Recent studies have shown that a number of networks associated to complex
systems belong to the new category of “scale–free small–world networks”. The
mathematical description of these networks is often based in probabilistic
models. However, deterministic models are useful to improve or complete
the analysis of these networks obtained by probabilsitic techniques or by simulation.
In this paper we introduce the concepts and basic models which
have been considered to analyze complex networks and we describe several
deterministic models which are obtained from complete graphs
