In the near future smart cities will utilise stronger sensors and IT controlled actuators, in order to monitor and potentially intervene in the flow of traffic and with environmental data. Through this particular process a lot of data is produced, which is aggregated and evaluated. With the aid of a platform, data, which is collected by sensors distributed throughout the city, becomes aggregated, prepared and shared with the public. Over the years, the business division of Digital Public Services (DPS), of the Fraunhofer FOKUS, offers experience in the design and implementation of data, especially open data portals. Thanks to the business division Software-based Networks (NGNI), the insitiut can develop far-reaching competences in the field of IoT and has its own successful M2M-Middleware. The Fraunhofer IZM applies its expertise to the project, within the field of microelectronics and sensor integration. The combination of these competences allows for the implementation of the general goal of the project, which is: the conception and prototypical development of a real-time data platform in combination with exemplary and distributed sensors.
