  1. WorldWide Sensor Web: Collective Action through Distributed Sensing Arpit Mehta

  2. Sensor Network • Comprised of a large number of densely deployed sensor nodes [1]

  3. Sensor Nodes • Sensor nodes have five subsystems • Processor • Memory • Radio • Sensor • Power Source

  4. How different are they from conventional networks [1]? • Limited Energy • Memory Constraint • E.g. 4KB of memory in Mica2 motes • Scalability • Bandwidth Limitation • Security • Dynamic Networks

  5. Sensor Network and the Web • Data Mining [2] • Integration with the real world [3] • Systems Challenge [3]

  6. 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]

  7. 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
