Model for Generation of Social Network Considering Human Mobility

Abstract

It is well known that many actual networks have the scale-free property that the degree distribution follows the power law. This property is found in many actual networks in the real world such as the Internet, WWW, a food chain network, an airline network, and a human relations network. As for a generation mechanism of a human relations network, we should consider the human mobility that, in general, a person moves around, meets another person, and makes friend relations stochastically. However, there are few models considering human mobility so far. In this paper, we propose a new model that generates a human relations network considering human mobility, and we show that this model has the scale-free property by numerical experiments.
