Reliable fault-tolerant sensors for distributed systems

“…j 4 To inject faults like the loss of information during communication, we simply disconnect nodes from the network. We show that FAMOUSO is able to detect late or lost data reliably [4]. It further enables the seamless reintegration of nodes into the distributed system if disconnection is only temporally.…”

“…Furthermore, it allows to enrich data with a validity value, and fusion nodes use these to determine results with a higher reliability [6]. Our publish/subscribe communication middleware FAMOUSO (Family of Adaptive Middleware for autonomOUs Sentient Objects) is responsible for the information dissemination and offers means to detect delayed or lost data [3,4,5]. Faults related to the processing are not considered as far (neither software nor hardware problems), due to the large number of existing research that bother with this topic (e. g., formal software verification).…”
