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

First Deployment in KenyaFirst Deployment in Kenya

The Main Idea

The ZebraNet Wildlife Tracker is an application to track zebras on the field

Special GPS equipped collars are attached to zebras.

Main operations

MonitoringSensor nodes are required to detect and track the

movement states of mobile objects

ReportingThe nodes that sense the objects need to report their

discoveries to the applications

These two operations are interleaved during the entire object tracking process

ZebraNet as Biology ResearchZebraNet 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

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.

) 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

) 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

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.
