  6. Sensor Web Overview

  7. Sensors Are Everywhere

  8. What is Sensor Web • A sensor network is a computer accessible network of many, spatially distributed devices using sensors to monitor conditions at different locations, such as temperature, sound, vibration, pressure, motion or pollutants. • A Sensor Web refers to web accessible sensor networks and archived sensor data that can be discovered and accessed using standard protocols and application program interfaces (APIs).

  9. Sensor Web Concept

  10. Background - Sensorweb

  11. Internet vs Sensorweb web of computers web of sensors Internet: connecting the world Sensorweb: sensing the world

  12. Internet vs Sensorweb Internet: circulatory system Sensorweb: nervous system

  13. Sensor Web Desires • Quicklydiscover sensors (secure or public) that can meet my needs – location, observables, quality, ability to task • Obtain sensor information in a standard encoding that is understandable by me and my software • Readily access sensor observations in a common manner, and in a form specific to my needs • Task sensors, when possible, to meet my specific needs • Subscribe to and receive alerts when a sensor measures a particular phenomenon

  14. Sensor Web Enablement Framework

  15. Integration Of ObservationsFrom A Variety Of Sensors We desire the ability to discover and integrate observations from any sensor that meets our needs

  16. Sensor Web Vision -1- • Sensors will be web accessible • Sensors and sensor data will be discoverable • Sensors will be self-describing to humans and software (using a standard encoding) • Most sensor observations will be easily accessible in real time over the web

  17. Sensor Web Vision -2- • Standardized web services will exist for accessing sensor information and sensor observations • Sensor systems will be capable of real-time mining of observations to find phenomena of immediate interest • Sensors will be capable of issuing alerts based on observations, as well as be able to respond to alerts issued by other sensors

  18. Sensor Web Vision -3- • Sensors and sensor nets will be able to act on their own (i.e. be autonomous) • Software will immediately be capable of geolocating and processing observations from a newly-discovered sensor
