  1. Common Goals and Infrastructures CGI3: Infrastructure Jonas Mellin CGI3: Current Status 2007-09-27

  2. Requirements Example • Developer of information fusion applications • Meet requirements • achieve properties of the system, e.g., • reliability • performance • testability • … • Available artefacts • products • operating systems • database management systems • network communication • UML, C++, … • methods • OMT, ROOM, SD, … Application Information fusion common features Artefacts CGI3: Current Status 2007-09-27

  3. Impact of infrastructure • The infrastructure has an impact on applications • Tandem computing (historical example, Borr 1984) • application running across multiple computers • different • operating systems • hardware • programming languages • services must be reliable • at first, all failures had to be managed by the application • then, they switched to transaction processing (databases) • improved • software productivity significantly (as expected) • average throughput, an unexpected result • smaller footprint, an unexpected result CGI3: Current Status 2007-09-27

  4. Emphasis • Tools, techniques, methods, and architectural issues • for information fusion application • execution • (development) • (maintenance) • In particular • active distributed real-time database management systems CGI3: Current Status 2007-09-27

  5. Current investigation • Purpose • develop architectures for • information fusion infrastructures • toolboxes • operating system features • middleware features • testable! • e.g., test critical issues in the wireless sensor network testbed • Motivation • CGI3 should serve other scenarios; it has been too narrow • JDL model open for interpretation • there may be too much freedom!! • a few more detailed architectures exists: match our req’s? • based on existing technologies CGI3: Current Status 2007-09-27

  6. Information fusion research as well as existing applications and infrastructures Example correctness property (information fusion) other requirements require data must have temporal validity (information fusion) Information fusion infrastructure ? fault avoidance strategy (dependability) require updating transactions must be timely (real-time databases) is a Database research require Real-time systems research Distributed systems research real-time scheduling strategy (real-time systems) Dependability research CGI3: Current Status 2007-09-27

  7. GQM modeling • GQM Modeling is employed • Goal (conceptual) • e.g., achieve reliable system from a developers’ perspective • Question (operational level) • e.g., is reliability an issue in the application scenario? • Metric (quantitative level) • e.g., Yes/No • Two iterations • develop/refine GQM • measure applications • classify/categorize • validate/prescribe • in 2nd iteration, target projects in which infrastructure is significant CGI3: Current Status 2007-09-27

  8. Expected results • Information fusion system architecture • services (goals, responsibilities, contracts) • critical services has been/can be tested • develop/refine toolbox • Improved ontology of IF architecture • precise, unambiguous, established concepts • incorporate established ontologies • Interesting research problems • in the gaps between • information fusion requirements • means (e.g., functions) provided by • different research fields • existing architectures of infrastructures CGI3: Current Status 2007-09-27

  9. Requirements Summary • Emphasis • Tools, techniques, methods, and architectural issues • for execution of information fusion applications • Currently: broadening scope • Developing requirements • of infrastructure • GQM modelling • theory • existing systems • Expected results • architecture • improved ontology • research problems Application Information fusion common features Artefacts CGI3: Current Status 2007-09-27
