information directly from contact (co-location) distributions. In this talk,
I will briefly describe ongoing work at Thomson Labs to combine the so-called
traditional (legacy) social network structures (friends of friends on facebook or linkedin etc) with
new mobility information (contact of contact in bluetooth
or wifi encounters).
Two uses of the
combined information: a) expanding and subtly altering one's social net

communities, from face-to-face encounters in Real Life); using the social
network (a priori, and learned, contacts and interests and tags) for
efficient dissemination of information in wireless ad hoc communities.
