A sensor network is a collection of low-power sensor nodes that can sense their environment, communicate wirelessly, and process data. Sensor networks operate autonomously in large numbers to monitor things like borders, battlefields, forests, habitats, infrastructure, and medical patients. They are application-specific based on factors like lifetime, cost, data needs, and environment.

8.  Sensors were integrated on
to the zebra’s neck.
 Consisted of 2 radios.
 Long range (base station)
 Short range (neighbors)
 These were used to monitor
the heart beat, body
temperature and frequency
of feeding

9.  Sensor networks are application specific
 Key application characteristics
Lifetime, cost, data rate, environment,
network topology, user interaction
 Must address the system aspects of
wireless sensor network design
