4. History
– Sensor networks exist already for a
long time
• Process industry (oil refineries, chemical
plants)
• Logistics
• Surveillance (CCTV)
• …
– Properties
• Closed networks
• Closed data sources
• No open standards (vendor specific
protocols)
– Technological developments…
• Hardware becomes smaller (=energy
efficient + cheap) and (internet) connectivity
is improving (bandwidth, stability, coverage)
and cheaper
• Standaards for interoperability are becoming
available (e.g. SWE, SSN, ONVIF)

8. Smart Objects…
>
Smart objects are physical or virtual devices with physical or virtual
sensors c.q. actuators (e.g. a security camera)
Hardware
Software
>
Virtual sensors = sensors that measure some virtual event and based on
this send alerts or notifications, e.g. a digital calendar alert or an alert
when someone enters your virtual house in Second Life
(www.secondlife.com)(the alert is send through the Second Life API to
e.g. your smart phone)

22. Examples sense-analyze-act en GEO (4)
> Smart Things and Social Media – Social web
of things “facebook of things”
> Alert when recycling bin is almost full, or when
it has been emptied

27. Real-time data brokers
>
>
>
>
Real-time data broker for networked objects and environments
Example https://xively.com/ (formely known as “Pachube”)
Collects and distributes data streams of sensors
Can send alerts, notifications and steer processes (actuating)

40. Mogelijke onderwerpen voor de Pilot
> Related to Pilot Use Cases or broader…
– Standaardization (technical + semantic)
• E.g. NL Profile for SOS and SPS
• Praktical use of OGC and W3C standards
