Distributed Computing in the Presence of Bounded Asynchrony

Research funding project
The availability of cheap and flexible COTS (commercially of the shelf) components opens up more and more application domains for embedded real-time systems. Next generation fault-tolerant embedded real-time systems will be employed in application domains like e.g. space, autonomy and artificial intelligence where timing uncertainty is induced just by the unpredictable environment. Another source for asynchrony are the intensive on demand computations which are inevitably necessary in such applications. Choosing timing bounds for normal operation according to rare worst-case computation requirements is costly and often not even required from a safety point of view. For those reasons, classic synchronous timing models are not suitable for building next-generation systems. The major scientific goal of the PhD project DCBA, which lies in the field of distributed computing theory, is the development of a new timing model for fault-tolerant distributed systems (the Theta-Model) and its application for solving fundamental agreement problems in this model.
