Di Giandomenico F., Itria M., Masci P., Nostro N. Networks of heterogeneous and dynamic interoperable systems: an approach to enhance dependability and performance properties. Lavoro sottomesso alla rivista RESS - Reliability Engineering & System Safety, Technical report, 2013.
Approaches to dependability and performance are challenged when systems are made up of networks of heterogeneous applications/devices, especially when operating in unpredictable open-world settings. The research community is tackling this problem and exploring means for enabling interoperability at the application level. The EU project Connect has developed a generic interoperability mechanism which relies on the on-the- y synthesis of Connectors", that is software bridges that enable and adapt communication among heterogeneous devices. Dependability and Performance are relevant aspects of the system. In our previous work, we have identi fied generic dependability mechanisms for enhancing the dependability of Con- nectors. In this work, we introduce a set of generic strategies for automating the selection and application of an appropriate dependability mechanism. A case study based on a global monitoring system for environment and security (GMES) is used as a means for demonstrating the approach.
