The Flock Mote Sensors Sing in Undergraduate
Curriculum

• Dae Young Jeong
• Supercomputing Lab.
• Yonsei Univ.

Introduction

• Educational excellence requires exposing students
  to the current edge of research.
• UW CSE have integrated the emerging field of
  wireless sensor networks into undergraduate
  computer engineering curriculum.
• Flock of Birds embedded systems project
  integrates the theory and practice of wireless
  sensor networks into curriculum.

4
A Flock of Birds

• A simple distributed system with combini-ng sound
  generation in an ad hoc network.
• Use timers, radio communication, and direct
  manipulation of hardware registers for sound
  production.

5
Hardware Software

• Atmel Atmega AVR-series microprocessor
• AVR-GCC C compiler
• Crossbow Mica2Dot platform
• TinyOS (event-based OS)

6
Course Work Procedure
Breadboard basics
Motes and TinyOS
Concert exam

• compile programs with AVR-GCC and upload them to
  ATmega16 processor on a breadboard.
• implement the flock algorithm in tinyOS.
  (event-driven programming)
• Two-hour concert of 50 motes in atrium.

7
Goals and simplified algorithm for each bird in
the flock.
8
Conclusion

• The project concluded with a concert in the
  atrium consisting of 50 bird motes that sang
  songs based on what other birds within radio
  range were singing.

9
In The Future

• The sound quality of the piezoelectric
  transducers was not exactly high fidelity.
• Light sensors Proximity sensors
• Rechargeable batteries power management

10
In UC Davis

• Implement a simple sensor networking data
  collection application using the Ember network
  hardware, Crossbow motes, TinyOS, NesC.
• Explore the tradeoff between power efficiency and
  ability.

11
In TecO

• Smart-Its provide sensors for collecting light,
  pressure, temperature, acceleration, and audio
  information.
