Historie
– Sensor netwerken bestaan al heel lang
• Procesindustrie (raffinaderijen)
• Logistiek
• Surveillance (CCTV)
• …
– Kenmerken
• Gesloten netwerken
• Gesloten data
• Geen standaarden (vendor specific
protocols)
– Ontwikkelingen
• Hardware steeds kleiner (=energy efficient +
goedkoop) en (internet) connectivity steeds
beter (bandbreedte, stabiliteit, dekking) en
goedkoper
• Standaarden voor uitwisseling in
ontwikkeling (bvb SWE, SSN, ONVIF)

Smart Objects…
> Smart objects zijn fysieke of virtuele devices met fysieke of virtuele
sensors c.q. actuators (bvb een security camera)
> Virtuele sensor = software (API) die via push of pull mechanismen alerts
en notificaties stuurt
> Bijvoorbeld een alert of notificatie als iemand je huis in second life
(virtuele wereld, zie www.secondlife.com) binnengaat (alert via de
SecondLife API naar bvb je smart phone)

– Standaardisatie (technisch + semantisch)
• Bijvoorbeeld NL Profiel voor SOS en SPS
• Praktische toepassing van OGC en W3C standaarden
– Sensor Catalog (metadata, vindbaarheid)
– Open Sensor Data
– Semantic Sensor Web
– Educatie en Onderzoek
– Uitwisselen praktijkervaringen
• Uitwisseling ervaringen op gebied van power supply (bvb
batterijverbruik), internet connectivity (bvb in afgelegen
gebieden), etc.
