contact — Haggle human proximity network (2005)
- Description
A network of the contacts between Bluetooth devices carried by attendees of the IEEE Infocom 2005 conference in Miami, recorded by the Haggle project (University of Cambridge and Intel Research Cambridge). Small Bluetooth devices (iMotes) were distributed to about 50 students attending a workshop of the conference on 7 March 2005, between lunch time and 5 pm, and collected on 10 March 2005 in the afternoon; each iMote scanned periodically for the other Bluetooth devices in its range, i.e. the other iMotes and any other device with Bluetooth (phones, laptops, ...), and recorded these sightings. Of the 54 iMotes distributed, 41 yielded useful data: two were lost, and the others did not record data because of failures with the batteries and packaging, or accidental resets; the contacts with these were removed from the traces of the other iMotes. The first six hours, when the participants were attending the same workshop, were also discarded. This is the experiment 3 of the Haggle traces (
imote-trace3), as sent by the authors and distributed in a GitHub repository.Each node is a device: nodes 1 to 41 are the iMotes, and nodes 42 to 274 are the other devices they recorded (each identified by its Bluetooth address, which is not given). A directed edge from device A to device B is a contact, i.e. an interval of time during which the iMote A recorded the device B in successive scans, so that pairs of devices are connected by several edges, one per contact (a multigraph). Only iMotes record contacts, and the contacts between two iMotes need not be mutual, since the scans of the iMotes were not synchronized and the sightings need not be symmetric. The times are given in seconds from the beginning of the trace, whose exact date and time is not given.
The network has the following properties:
- (Node)
is_imote: whether the device is one of the iMotes (otherwise an external device). - (Edge)
time: the first time at which the iMote recorded the device in the contact, in seconds from the beginning of the trace. - (Edge)
end_time: the last time at which it recorded it (equal totimefor contacts seen in a single scan). - (Edge)
duration: the difference of these two times, in seconds. - (Edge)
contact_number: the number of the contact among those of the same pair of devices (1, 2, ...). - (Edge)
gap: the time between the beginning of the contact and the end of the previous contact of the same pair, in seconds (0 for the first contact of a pair).
