Trace of wireless contacts, social connections, and user interests,
performed in an academic environment for 63 days, with 72 participants

Contributed by Radu I. Ciobanu, Ciprian Dobre.

Wireless contacts trace collected at the University Politehnica
of Bucharest in the spring of 2012, using an application entitled
HYCCUPS Tracer (http://hyccups.hpc.pub.ro), with the purpose of
collecting contextual data from Android smartphones. It was run
in the background and collected availability and mobile
interaction information such as usage statistics, user activity,
battery statistics, or sensor data, but it also gathered
information about a device's encounters with other nodes or with
wireless access points. Encounter collection was performed using
AllJoyn. The data was collected by constructing and deleting
wireless sessions using the AllJoyn framework based on
WiFi. Tracing was executed asynchronously. The duration of the
tracing experiment was 63 days, between March and May 2012, and
had 72 participants, out of which only 42 had at least one
contact. By analyzing the participants' Facebook profiles, the
social connections matrix was extracted, as well as the users'
interests. The trace (and others from the CRAWDAD collection) is
parsed within the MobEmu simulator (used in all UPB's papers),
publicly available at https://github.com/raduciobanu/mobemu.
