Sensor Network Comprised of a large number of densely

deployed sensor nodes [1]

Sensor NodesSensor nodes have five subsystems

ProcessorMemoryRadio SensorPower Source

How different are they from conventional networks [1]?Limited Energy Memory Constraint

E.g. 4KB of memory in Mica2 motes

ScalabilityBandwidth LimitationSecurityDynamic Networks

Sensor Network and the Web

Data Mining [2]

Integration with the real world [3]

Systems Challenge [3]

Some Applications Environmental Monitoring

Active Volcano Monitoring [4]Underwater Monitoring System [5]PODS-A Remote Ecological Micro-Sensor

Network [6]

Home Automation

Parking Space Finder [7]

The Ring Sensor [8]

The Future[9] Planet wide collection of data

Query can be posed from anywhere via the internet

Real time collection of data

Developers of sensing applications will be able to deploy their services on this distributed infrastructure
