CSCI 7143-001: Sensor Networks

Announcements

Fall 2002

Nov. 2002

• Future announcements will be via our email list.

Oct.30, 2002

• 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 above.

Oct.22, 2002

• 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 glitches.

• Reserving time slots with the Motes/workstations in ECCS 102
  • I've set up a Yahoo Groups Calendar that will allow us to reserve time slots to work with the Motes in ECCS 102.  Details are highlighted in red towards the bottom of the Programming Assignment/Mini-Project description.

Oct.11, 2002

• 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 now.
• The paper schedule for Monday 10/14 is now available.  
  • 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 course:
    • Apr. 23: Chapter 8: Symmetric Key Cryptography, Block/Stream Ciphers, Public Key Cryptography
    • Apr. 25: Chapter 8: Authentication, Integrity, Non-Repudiation, SSL
    • Apr. 30: Chapter 8: IPSec, Firewalls

Oct. 8, 2002

• 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: sensornet_fall2002@cs.colorado.edu
  • 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.

Oct. 5, 2002

• The next two papers to read for Monday are available on the Web site. 

Oct. 2, 2002:

• Programming Assignment/Mini-Project available here

Sept. 30, 2002:

• Mobicom 2002 papers

• WSNA 2002 sensor networking papers

• WISE 2002 security papers

Sept. 21, 2002:

• Mini-project outline:

  • 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.

• Due date for the one-page project proposals has been extended until Oct. 2, due to the recent absences of Prof. Han.

• Prof. Han will be away on Wed. Sept. 25 and a substitute professor is currently being sought.

• Project suggestions should be available soon.

Sept. 18, 2002

• Prof. Han will be away on Wed. Sept. 18.  Substitute professor will be Prof. Shivakant Mishra.
