Description:
Communication platforms for ubiquitous computing need to
be flexible, self-organizing, highly scalable and energy efficient, because in
the envisioned scenarios a large number of autonomous entities communicate
in potentially unpredictable ways. Short-range wireless technologies
form the basis of such communication platforms. In this paper we investigate
device discovery in Bluetooth, a candidate wireless technology for
ubiquitous computing. Detecting new devices accounts for a significant
portion of the total energy consumption in Bluetooth. It is argued that
the standard Bluetooth rendezvous protocols for device detection are not
well suited for ubiquitous computing scenarios, because they do not scale
to a large number of devices, take too long to complete, and consume too
much energy. Based on theoretical considerations, practical experiments
and simulation results, recommendations for choosing inquiry parameters
are given that optimize discovery performance. We prop
