CSCI 7143-001: Sensor
Future announcements will be via our email list.
Grading of late programming assignments: I am
willing to allow late programming assignments, but 10% of the grade will be
taken off for each late day. After 3 days, i.e. after Saturday Nov. 2 midnight, I will no longer accept late programming assignments. For
the group working on the Crickets, your packet flooding assignment on the
Crickets is due by Wednesday Nov. 6, with the same late grading policy as
For future class presentations, please send
me your Powerpoint slides the night before your presentation. Paper
reviews will continue to be due before class on the day of the paper
discussion. For my part, I will be assigning the paper
presentations a week in advance, i.e. every Wednesday I'll assign presenters
for each of the papers we will be reading for the following week's Monday
and Wednesday classes. I've been pleased with the presentations and
discussions thus far. This new policy will help prevent last-minute
Reserving time slots
with the Motes/workstations in ECCS 102
ECCS 102 IS OPERATIONAL
- There should be two Mote kits, one connected to a
laptop and other to a desktop, in room ECCS 102, for the Sensor
Networks seminar. This should be enough for your programming
assignment. A reminder to request the metal key for ECCS 102 from
Stephanie Morris in ECOT 722.
- We may wind up setting up individual and/or team
accounts on Linux boxes, rather than the single class account we have
- The paper schedule for Monday 10/14 is now
- You only need to read and review pp. 1-8. We'll
read and review the rest of the paper on Wednesday (as well as the
"DOS attacks on sensor nets" paper). Take your time to
understand basic security concepts, and make use of the recommended
tutorial slides. See also the slides from my network systems
ANNOUNCEMENT #1: ROOM ACCESS AND
CHANGE TO NEW ROOM ECCS 102
- We now have our own lab, room ECCS 102, for the Sensor
Networks seminar. There is space in there for a few computers and
workstations and we don't have to share it with anyone. This is much
better than ECCS 123, which was crowded and filled with equipment.
You need to request a
metal key for the new room ECCS 102 from Stephanie Morris in ECOT 722.
She will require you to fill out a form, which you then need to take
down to the stadium to obtain the key. We should have the workstations,
laptops, and Motes installed in the room by sometime tomorrow afternoon,
ready for you to begin your programming assignments. If you want
access to the 102 lab during Fall Break, you should obtain the keys
either Wednesday morning or early afternoon.
- New mailing list for the class:
- Inform you of class announcements (usually also on the Web page)
- For you to post questions and discussions, e.g. about the programming
assignment on the Motes or project-related issues later in the semester
- The list should be operational by Wednesday afternoon.

Build a packet flooding protocol on sensor
Motes. This protocol should:
allow a basestation to send data to individual
sensor Motes. This will be demonstrated by lighting green LEDs
on the destination sensor Mote.
allow a sensor Mote to send its current sensor
readings to the basestation. This will be verified by a
software application, on a laptop connected to the basestation, that
will plot the current readings of each of the sensors in the network
be efficient in both directions, such that
packets should not be repeated unnecessarily, e.g. in a cyclical
loop. This will be verified either by lighting LEDs on the
Motes or by inspecting a packet trace of network behavior.
Due date for the mini-project on the Motes is
tentatively Oct. 30.
Motes and the laptop setup for programming them
will become available for you after Oct. 2. They will be available
in the lab, either ECCS 123 or possibly in the new DLC building,
depending upon departmental space movement. These Motes should be
shared, and we will provide a policy for sharing them at a later time.
date for the one-page project proposals has been extended until Oct. 2, due
to the recent absences of Prof. Han.
Han will be away on Wed. Sept. 25 and a substitute professor is currently
suggestions should be available soon.
