 The
PADS team at ISI has been heavily involved in developing and
utilizing embedded Linux on handheld computers for Defense
applications. We are mostly active in the www.handhelds.org
community. Our research focus has been to use handheld Linux
machines as prototype platforms and user interface front ends to wireless
distributed microsensor networks. On the PADS project, we have been
focusing on power analysis of these systems and algorithms for video
surveillance and video conferencing. Here is a list of things we
have been doing in this area:
- We performed some very early power analysis on the iPAQ last year
and identified most of the major power consumers. We added sleep
(and more importantly wakeup :-) mode to the www.handhelds.org
distribution so your iPAQ doesn't have to reboot Linux every time you
hit the power button! Here is a graduate
student presentation on the power consumption of iPAQ.
- In March 2001, we experimented with a number of iPAQ PDAs in the
desert at 29 Palms, California. We ran Vic on an iPAQ over an 802.11
Ethernet infrastructure (in the middle of the desert no-less).
The video was broadcasted from a laptop. We also used iPAQs to gather
GPS ground truth and mySQL it into a database server. Photos can
be found on our sister project page Dynamic
Sensor Networks.
- We have completed a port of the Winnov
Videum PCMCIA camera driver for iPAQ. We plan to distribute
a number of video lunch-boxes with iPAQs and Videum cameras for an
integrated map status and video surveillance demo.
- In November 2001, we are going back to the desert and are taking
tons more iPAQs. They are a heck of a lot lighter than all of
the instrumentation laptops we carried back in the Spring! We
plan to have three stationary video surveillance iPAQs, our precious
BackPAQ sleeve on a mobile user, three more iPAQs in lunchboxes
gathering and broadcasting GPS ground-truth data, and one or two
soldier map interface display handhelds. Wow. Will publish
pictures (and video hopefully) from our trek as soon as we pry the
sand out of our... laptop keyboards.
- Sound like fun? We have openings for a small number graduate
student internships this summer (PhD preferred, but top-notch
required). Send a resume to pads-resumes@pads.east.isi.edu.
