For the development of wireless communication technologies and
miniaturization of wireless devices, portable wireless devices with
Bluetooth and Wi-Fi have been widely distributed and people have
freely carried around them in recent years.
We conducted mobile wireless communication experiments by carrying
around PDAs to scan and log nearby Bluetooth and Wi-Fi devices for
a long time.
Since the devices with Bluetooth and Wi-Fi are often possessed by
humans, recorded information is expected to be a sample drawn from
contact frequency of passing-by (or encountered) humans.
By using obtained data, we investigated the contact frequency of
humans and found that it universally obeys a power law. Moreover,
we also found that the number of once-in-a-lifetime meetings, i.e.,
the number of devices encountered only once reached 90 percent of
the total number of encountered devices. To explain this phenomenon
of ``inequality of meetings" theoretically, we proposed ``Homesick
L\'evy Walk (HLW)" as a simple mobility model. |
