1. Introduction

Sensorweb and Internet

of Things

www.geodan.nl

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)

Internet of Things (Gartner Hype Cycle)

Internet connected smart objects

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)

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)

streams)

6. Privacy

Privacy (NRC Saturday 15th February 2014)

www.geodan.nl

Statements…

www.geodan.nl

Privacy

> The feeling of being spied upon by the Government (control state)

7. Possible subjects

for SW & IoT Pilot… …

www.geodan.nl

> 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

– Sensor Catalog (meta data, findability)

– Open Sensor Data

– Semantic Sensor Web

– Education and Research

– Exchange of user experiences

• In the areas of hardware (power supply, battery life)

• Internet connectivity (bvb in remote areas)

• …
