The University of Twente leads in respect of research into the Internet of Things. All kinds of devices and sensors will soon communicate with one another, often wirelessly and autonomously. That might start with an intelligent thermostat, and might soon extend to vehicles that communicate with each other. The Smart Cities vision can already be tested within the compact environment of Kennispark Twente. There, sensors are able to provide a wealth of information, for example, about traffic and parking movements, water and air quality, energy consumption, or vibrations in buildings. How all that metadata is interlinked is a compelling issue. At the same time, it raises questions in terms of security – is the network safe from hackers? – and privacy. The Pervasive Systems (CTIT) group has already created the foundation with the establishment of the Twente IoT platform.
