  1. Wireless Sensor Networks The ZebraNet Wildlife Tracker

  2. ZebraNet A sensor network consists of several data collecting nodes which communicate with a base station that compiles the data from them

  3. ZebraNet Hardware

  4. Motivation Computer systems Perspective: Develop, evaluate, implement, and test systems that integrate computing, wireless communication, and non-volatile storage along with global positioning systems (GPS) and other sensors Biology Perspective: perform novel studies of Animals migration patterns Eating habits Inter- and intra-species interactions The impact of human action on their activity

  5. Basic Opearation

  6. Basic Operation Sensor Nodes periodically collects data and store Information about: Animal's location Heart rate Body temperature Feeding frequency. This information will be transmitted back to the base station when the researchers fly or drive by within a certain distance from the nodes. Hence, scientists can enjoy their observation efforts without disturbing the animals.

  7. ZebraNet Design • Lightweight • Energy-efficient • Detailed 24/7 archival position logs • GPS-enabled • „No fixed base station (no cellular service) • Peer-to-peer routing and data storage • „Restricted human access to systems ➨ Planned 1 year of autonomous operation
