What: IPSN '08 Extreme Sensing Competition
When: April 22-24, 2008
Deadline: April 10, 2008
Details: http://www.cs.virginia.edu/~whitehouse/ipsn08competition
IPSN '08 will be hosting the second Extreme Sensing competitionon April
22-24, 2008. This year's competition is a "skoke hunt", where a /skoke/
is a mote, cell phone, or PDA that is designed to be easily located by
its creators, but hard for anybody else to find. Each team must bring
four skokes that will be given to attendees of the conference, who will
carry them throughout the conference. All teams must then try to
identify as many attendees that have skokes as possible. All skokes must
transmit a pre-defined beacon message at least once a minute, but a team
can equip its own skokes with any number of sensors to relay information
about their own whereabouts, to eavesdrop on other skokes, or to jam
their messages. Teams can use at most four /detector nodes/ that can be
equipped with any technology to find skokes, but must be completely
passive, ie. the detector nodes may not transmit any radio messages or
other signals. The team with the most skokesafter 36 hours wins! For
more details about the competition, and how to enter, visit the URL
listed above.
