1. ZebraNet Hardware Design Experiences in ZebraNet - 2004 Presented by Zuhal Tepecik

2. Hardware Design ZebraNet is a mobile sensor system which consists of sensor nodes built into collars on zebras to take positional readings using GPS

3. Hardware Design Versions

4. Constraints Memory constraint Energy constraint Device access constraint Radio packet size constraint GPS sensing time constraint Flash storage constraint

5. Energy issues System Level Energy Management dual clock scheme on-the-fly processing timely use of components Power Supplies linear regulators switch converters Batteries and Solar Recharge Solar Cells Batteries

6. Operation Schedule CPU wake up/Radio - Flash power on Radio transmitting / receiving start Network communication time Radio - Flash power off GPS power on GPS sensing time GPS power off / Flash power on CPU sleep / Flash power off

7. Deployment In Kenya, the system deployed on Zebras at the 100 sq km. The radio range is measured between 100 m to 1.2 km; some conditions; such as grazing of Zebras, cause radio range decrease Zebra location data is given to biologists to learn about Zebra movement difference from day to night

8. Conclusion Developed fully-functional highly mobile energy efficient sensing system
