METHOD AND DEVICE FOR OPERATING A SYSTEM WITH DISTRIBUTED SENSORS

摘要

Distributed devices with sensors each maintain a copy of a common model. The devices each perform updates of state variables of the model in response to update information received from other devices in the group. Each device derives update information from its own sensor and decides whether or not to share the update information with the other devices. If it does not share the information the devices does not use the information itself either. Thus it is ensured that all devices keep their models consistent. Each device applies an evaluation function to the update information in the context of its current model to determine whether or not share the update information. The evaluation function may be adapted dependent on available communication bandwidth or information needs indicated by a device from a controlling layer that uses information from the model.
