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
