Resumen
The paper examines the implementation of one approach to alternative presentation of location information in social networks. The classic model consists in placing a record (message) with some real or virtual place, which is described by a pair of geographical coordinates (latitude, longitude). Further, using the social networking API, the user can get a list of members of his social circle who are in a given place or nearby. For business applications, these location markers provide the basis for service offerings. This paper looks at the network proximity approach, where data is transmitted directly to mobile users in the vicinity. It completely excludes the handling of geo-referenced data as well as the need to store location data in a third-party storage location. This approach does not store location information on a social network, but rather shares social network data (a link to a profile) directly with other nearby users. This approach solves several issues at once, from security to scalability. This paper looks at the implementation of such a model for the social network VKontakte.
