Introduction to Small-World Networks and Scale-Free Networks

WebAbstract. In this chapter we will introduce two famous network models that arose much interest in recent years: The small-world model of Duncan Watts and Steven Strogatz [615] and scale-free or power-law networks, first presented by the Faloutsos brethren [201] and filled with life by a model of Albert- László Barabási and Réka Alberts [60]. WebIt is known that a wide variety of abstract graphs exhibit the small-world property, e.g., random graphs and scale-free networks. Further, real world networks such as the World Wide Web and the metabolic network also exhibit this property. In the scientific literature on networks, there is some ambiguity associated with the term "small world".

The main mechanism to construct small-world networks is the Watts–Strogatz mechanism. Small-world networks can also be introduced with time-delay, which will not only produce fractals but also chaos under the right conditions, or transition to chaos in dynamics networks. Degree–diameter graphs are constructed such that the number of neighbors each vertex in the network has is bounded, while the distance from any given vertex in the network to any other ver… WebScale-free = powerlaw distribution of degrees.

WebFeb 4, 2003 · In contrast to the diameter of regular random networks or small-world networks, which is known to be d∼ln N, we show, using analytical arguments, that scale-free networks with 2< λ<3 have a much smaller diameter, behaving as d∼ln ln N. For λ= 3, our analysis yields d ∼ln N /ln ln N, as obtained by Bollobas and Riordan, while for λ >3, d∼ln N.
