Introduction

• Real-world habitat monitoring
• Working with members of life scientist
• Difficulty of sensor network implementation for
  habitat
• The result of wireless sensor-based monitoring
• Sensor network deployment

4
Habitat monitoring

• Internet access
• Hierarchical network
• Internet connectivity and database systems
• Sensor network longevity
• Run for 9 months
• Operating off-the-grid
• Disconnected operation remains a possibility
• Management at-a-distance
• Remoteness of the field

5
Habitat monitoring (cont.)

• Inconspicuous operation
• Sensors and sampling
• Sense light, temperature, infrared, humidity
• Data archiving
• Data mining and analysis

6
System architecture

• The lowest level of the sensing application
• Autonomous sensor nodes
• Collects environmental data
• Programmable unit provided
• Networked sensors offer two advantages
• Can be re-tasked
• Can communicate easily
• Communicate and coordinate with one another
• Internet is needed
• To propagate data
• To use sensor patch
