The idea of “smart sensing” includes a permanent monitoring and evaluation of sensor data related to possible measurement faults. This concept requires a fault detection chain covering all relevant fault types of a specific sensor. Additionally, the fault detection components have to provide a high precision in order to generate a reliable(More)
The variable acquisition of distributed sensor perception promises an effective utilization of these data across different applications. Multiple observations enable an increase in the quality of the system output. However, the dynamic composition disables all off-line optimization approaches, especially for sensor-application-scheduling. This paper(More)
Distributed applications dealing with data from networked sensors need some indication about the quality of remote information. This paper describes how to derive a dynamic validity value that represents a measure for the confidence in remote sensor data. In contrast to conventional systems which treats a typical processing chain as a whole, this paper(More)
Modern sensor-actuator applications combine a large number of components (sensing devices, processing nodes, networks) and implementing complex interactions between them. Due to failures and other sensor inherent insufficiencies the intended control function is adversely affected. This cannot be tolerated in safety critical applications. In some cases(More)
Networking communications play an important role to secure a dependable and timely operation of distributed and real-time embedded system applications; however, an effective real-time support is not yet properly addressed in the wireless realm. This paper presents Wi-STARK, a novel architecture for resilient and real-time wireless communications within an(More)
