In computer science, the small-world phenomenon (although it is not typically called that) is used in the development of secure peer-to-peer protocols, novel routing algorithms for the Internet and ad hoc wireless networks, and search algorithms for communication networks of all kinds.
The “ small-world phenomenon ” is a characteristic that differentiates OSN graphs from graphs in general. The phenomenon represents the observation that only a small number of connections are necessary to link two nodes in very large OSN graphs.
La teoria del mondo piccolo o dei piccoli mondi, o effetto del mondo piccolo è una teoria matematica e sociologica che sostiene che tutte le reti complesse presenti in natura sono tali che due nodi qualunque possono essere collegati da un percorso costituito da un numero relativamente piccolo di collegamenti [1].
Introduction. The Small-World Phenomenon. A social network exhibits the small-world phenomenon if, roughly speaking, any two individuals in the network are likely to be connected through a short sequence of intermediate acquaintances.
We introduce and define three types of small worlds: small worlds based on the diameter of the network (SWD), those based on the average geodesic distance between nodes (SWA), and those based on the median geodesic distance (SWMd). These types of networks are defined as limiting properties of sequences of sets.
A small-world network is a graph characterized by a high clustering coefficient and low distances. On an example of social network, high clustering implies the high probability that two friends of one person are friends themselves.

We introduce and define three types of small worlds: small worlds based on the diameter of the network (SWD), those based on the average geodesic distance between nodes (SWA), and those based on the median geodesic distance (SWMd).
