  1. The ZebraNet Wild Life Tracker Department of Electrical Engineering Princeton University

  2. Road Map • Background • ZebraNet: Problem Statement • ZebraNet Design Details • Protocol Design Tradeoffs • Current Status

  3. Background • Sensor nets • In areas without cellular coverage • Using peer-to-peer communication • With “ad hoc” methods for discovering network routes and keeping them up to date

  4. ZebraNet • Biologists want to track animals • ZebraNet: Wireless ad hoc network of zebras… • Intelligent tracking collars placed on sampled set of zebras • Sensor network: data collected includes GPS position info, temperature,

  5. Current GPS position sample every 3 minutes Sun/Shade indication Detailed position sampling: Standing still or moving? Speed? “Step rate”. Future Head up or down: “bite rate” Body temperature Heart rate Interactions with other species ZebraCam Data to track: What are the sensors in this net?

  6. Challenge • Need sufficiently long range • Power generation & storage: Power efficiency • serious bandwidth and computational needs • Reliability & fault tolerance • Good physical design for ruggedness • Variable frequency for use in US & Kenya

  7. ZebraNet Block Diagram

  8. ZebraNet sensor • Weight: 1090 grams (2.4lbs) • Designed to operate for 5 days without solar recharge • Energy saving tricks • Baby picture

  9. Basic Operation System • Nodes collect logs of GPS position and other information. • Peer-to-peer communication aggregates data back to researcher base station • Research station is not fixed. Rather, it moves and is only intermittently available

  10. Protocol tradeoff • Flooding: Every 3 minutes, zebras look for other zebras in range. Send to everyone they find. • History-Based: Every 3 minutes, zebras look for others in range. Of the ones found, only send to one: the one with the best success rate at delivering data.

  11. Current Status • January 2-24, 2004: ZebraNet heads to Kenya for its first test deployment! They were at the Mpala Research Centre and deploying nodes on zebras at the Sweetwaters Reserve.
