Active diagnosis in real time embedded computer systems increases the overall reliability of the system by performing error detection and fault recovery. Real time databases and diagnostic queries are a common solution to realize active diagnosis. This paper presents a technique to optimize the diagnostic queries in a fault tolerant real time embedded system. A directed graph called the DMG (Diagnostic...
Active diagnosis aims at significantly improving system reliability by computing diagnostic information at run-time for fault isolation and online error recovery. The presented work extends semantic techniques, usually used in large-scale IT systems, for active diagnosis in open embedded real time systems. Open embedded systems (e.g., ambient assisted living for elderly care, critical infrastructures,...
