1. Presentation on “WSN Application” (ZebraNet) Presented by: Belal Abdullah Abdulmaged 28\11\2011

2. The Main Idea “In many applications, a wireless network needs to detect and track mobile targets, and disseminate the sensing data to mobile sinks” Zebra Net Application The users are the biologists. Tracking the movement of wild animals in wildlife preserves

3. First Deployment in Kenya First Deployment in Kenya

4. The Main Idea The ZebraNet Wildlife Tracker is an application to track zebras on the field Special GPS equipped collars are attached to zebras.

5. Main operations Monitoring Sensor nodes are required to detect and track the movement states of mobile objects Reporting The nodes that sense the objects need to report their discoveries to the applications These two operations are interleaved during the entire object tracking process

6. ZebraNet as Biology Research Goal: Biologists want to track animals long-term, over long distances Interactions within a species? Interactions between species? Impact of human development? The users are the biologists. Location, speed, direction, size, and shape

7. ZebraNet as Computing Research Data Base station (car or plane) Data Store-and-forward communications Data Tracking node with CPU, FLASH, radio and GPS

8. ZebraNet vs. Other Sensor Nets – Track animals long term and over long distances – All sensing nodes are mobile – Large area: 100’s-1000s sq kilometers – “Coarse-Grained” nodes – GPS on-board – Long-running and autonomous.

9. ِ A Day in the life of a Zebra Two kinds of Zebras Grevy’s zebra Forms large loosely-bounded herds Plains zebra More common Forms tight-knit uni-male multi-female ”harems” Possible to add collar just to the male From time to time meet up with other zebras to form herds, for an example at water holes

10. ِ A Day in the life of a Zebra Movement patterns Grazing Graze-walking Fast-moving Zebras spend most day grazing and head for water about once a day Zebras tend not to have long periods of motionless sleep

11. Innovation January 2-24, 2004: ZebraNet heads to Kenya for its first test deployment! At the Mpala Research Center and deploying nodes on zebras at the Sweet waters Reserve.
