Field of Research

To build next generation ubiquitous computing systems cost effectiveness, low power consumption, reliability and scalability have to be taken into account when the hardware platform is defined. An emphasis is put on standard wireless communication technologies like Bluetooth and its low-power pendant Bluetooth Low Energy, RFID and UWB. MEMS technology is used to save cost and to increase reliability.

Finding the right system architecture for such large scale systems like an indoor navigation system for a museum or public buildings could be a hard and error prone task. Therefore, the modeling of the system in advance plays an important role. The model consists of virtual prototypes of wireless sensors nodes which can be combined in an easy and scalable fashion to model large scale wireless sensor networks. To get a system behavior that corresponds as much as possible to the operation environment physical parameters like obstacles, fault models or power consumption can be annotated to the real prototypes. The parameters are assembled from small scale real wireless sensor network prototypes.

The research activities are funded by the Baden-W├╝rttemberg Stiftung under Grant 22-729.81-7-5/27 (F├Ârderprogramm Informationstechnik Baden-W├╝rttemberg BW-FIT). In cooperation with the Center for Art and Media Karlsruhe (ZKM), FZI combines art with the newest high precise indoor localization for multimedia-based exhibitions. In a first project, the localization was used for localizing models during a world premiere of multimedia composition
