  • Abstract: Embedded systems are often distributed among several nodes within their systems. The nodes in such systems are physically disjoint and communicate via a network or a bus to accomplish a common goal, e.g. a typical sensor-actor relation. If the system is not only distributed but also a real-time system, paths typically have to comply with hard deadlines. In a static system, path dependencies can be pre-calculated off-line and checked to ensure that all deadlines are met. With the trend for reconfigurable systems the path deadline analysis and the search for a valid configuration is shifted onto the system itself. While each application in a distributed real-time system is usually bound to a specific node in the system, the scheduling policy on a node is free to be chosen. In this thesis I will investigate different distributed contract-based approaches to solve path latency constraints for distributed real-time systems.
