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)

Increasing numbers of smart objects…

Smart Objects…
> Smart objects are physical or virtual devices with physical or virtual
sensors c.q. actuators (e.g. a security camera)
> 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)
