Misc Notes

Definitions

Close Proximity Incident

• At least 30 mins within a 2m radius

Engineering

• accelerometer as a reasonably natural random source/seed
• easily add temperature sensor or pulse/ox
  • Increases power consumption

Radio

• Randomize scan/broadcast to counter interference/dense net collision
• Variable scan interval based on perceived density (counters collision-based losses)
• Increase scanning frequency
  • Need more battery/power!

Power

• Add more cells by default, 80mAh cell is wimpy

Readings

• Power Management
  • An adaptive wakeup scheme to support fast routing in sensor networks
