Emergence of encounter networks due to human mobility

Abstract

There is a burst of work on human mobility and encounter networks. However, the connection between these two important fields just begun recently. It is clear that both are closely related: Mobility generates encounters, and these encounters might give rise to contagion phenomena or even friendship. We model a set of random walkers that visit locations in space following a strategy akin to Lévy flights. We measure the encounters in space and time and establish a link between walkers after they coincide several times. This generates a temporal network that is characterized by global quantities. We compare this dynamics with real data for two cities: New York City and Tokyo. We use data from the location-based social network Foursquare and obtain the emergent temporal encounter network, for these two cities, that we compare with our model. We found long-range (Lévy-like) distributions for traveled distances and time intervals that characterize the emergent social network due to human mobility. Studying this connection is important for several fields like epidemics, social influence, voting, contagion models, behavioral adoption and diffusion of ideas.

Cluster Aware Mobility Encounter Dataset Enlargement

“…There were dramatic deviations from realism indicating serious flaws in existing models and their inadequacy as testbed tools for any type of performance evaluation purposes. Riascos and Mateos [9] have analyzed the human urban mobility in New York and Tokyo based on the data harvested from Foursquare application.…”

Territory as a Feature of the State in Terms of Modern Public Relations Development

“…The growing mobility of people and the use of technologies affect the relations that are connected with it. Electronic devices and software, on the one hand, make it possible to identify the location of a person, but at the same time it eliminates the necessity for direct contact with that person [28]. There is no need for direct interaction to commit legal actions, and the territory on which some legal relations occur does not matter at all and, thus, isn't taken into consideration within the current system of regulation.…”

A Novel Effective Indicator of Weighted Inter-City Human Mobility Networks to Estimate Economic Development

“…At the collective level, the spatial-temporal patterns of aggregate human mobility were widely used in urban planning [26], traffic forecasting [27], and the spread prevention of biological [28], and mobile viruses [29]. As a result, human mobility, on the one hand, made the world smaller [30]; on the other hand, led to city attraction and economic strength. Thus, human mobility has potential for estimating economic growth.…”
