On Small-World Networks: Survey and Properties Analysis
share
Complex networks has been a hot topic of research over the past several years over crossing many disciplines, starting from mathematics and computer science and ending by the social and biological sciences. Random graphs were studied to observe the qualitative features they have in common in planetary scale data sets which helps us to project the insights proven to real world networks. In this paper, We survey the particular case of small-world phenomena and decentralized search algorithms. We start by explaining the first empirical study for the six degrees of separation phenomenon in social networks; then we review some of the probabilistic network models based on this work, elaborating how these models tried to explain the phenomenon properties, and lastly, we review few of the recent empirical studies empowered by these models. Finally, some future works are proposed in this area of research.
