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]. These models describe some structural aspects of most real-world networks. The most prevalent network structure of small-world networks is a local mesh-like part combined with some random edges that make the network small.
