    "abstract": "We propose a model of mobile agents to construct social networks, based on a\nsystem of moving particles by keeping track of the collisions during their\npermanence in the system. We reproduce not only the degree distribution,\nclustering coefficient and shortest path length of a large data base of\nempirical friendship networks recently collected, but also some features\nrelated with their community structure. The model is completely characterized\nby the collision rate and above a critical collision rate we find the emergence\nof a giant cluster in the universality class of two-dimensional percolation.\nMoreover, we propose possible schemes to reproduce other networks of particular\nsocial contacts, namely sexual contacts.",
