Everything you wanted to know aboutLizardNet

• By the LizardNet team

• Alejo The Biologist Enriquez
• Kapambwe Sippy Cups! Kangombe
• James The Yellow Dart Segedy

Presentation Format

• Background Lizards
• Wireless Networks
• Hardware and Software
• Progress Report
• Questions

3
Wireless Network Applications

• The CS department wants to get a wireless network
  working
• Field equipment without wires
• Meteorology
• Environmental data
• Homeland security
• The Biologist wants to get data on lizard
  thermoregulation

4
Thermo-what?

• Thermoregulation
• Regulation of body
• temperature
• Species studied
• Sceloporus occidentalis
• Lizards have an optimal body temperature, but
  they are cold-blooded
• They stay at the same temperature by moving
  around to different areas

5
Why thermoregulation?

• Traditional data taken in long intervals
• Constant, near-real-time temp data is much more
  informative
• Would lead to better understanding of lizard
  microhabitats
• Could give insight into how often lizards move
• Long-term data informative on energetics of
  lizard ecology

6
What is LizardNet?

• An experiment in embedded sensor networking
• Wireless mote
• Motes can be programmed to detect things like
  temperature and light

Holy tiny computers, Batman!
7
Tell me more.

• Hardware from
• Version MicaZ (uses standard radio frequency)
• Operating system SOS (Why?)
• Teaming up with UCLA group
• Sensor board MDA300

8
How does all this work?

• Motes talk to one another
• One is plugged into a computer (the NIC)
• In the field, a base station is used sometimes

Example network system from xbow.com
9
Tell me more about the software

• SOS - mote operating system
• Developed by Roy Shea (HMC 02), Ram Kumar, and
  Simon Han
• Static vs. Dynamic Code (modules)

10
The MDA300

• SHT15 (internal)
• External Temp Sensor
• There is currently no driver support for the
  MDA300

11
Deployment

• Issues with deployment
• Location
• Weatherproof cases
• Power usage
• Managing the distances
• Getting the data back
• We currently have selected a deployment site at
  BFS
• What makes one location better than another?

12
Test Location Map
13
The Progress Report

• Get hardware (MicaZs, Serial Cable, etc)
• Get software (SOS)
• Get hardware to ACCEPT software
• Make motes blink their LEDs
• Make motes hop their information
• Receive temperature readings from inside
  refrigerator
• Map out test location for transmission power
• Write driver for SHT15

14
The Progress Report, continued

• Write more drivers for MDA300
• Figure out exactly what power levels we need for
  broadcasting
• Get base station thing figured out
• Make weatherproof containers for motes
• Deploy motes
• Read and analyze data
• Give presentation

15
Any Questions?

• Dont be shy!

16
Field Trip!

• Lets all go look at blinking LEDs
