Abstract
Interoperability is the ability for two systems to exchange, understand and use each other's data, and is a long-standing problem in the field of distributed systems. However, the emergence of pervasive computing and the Internet of Things have brought about new challenges to achieving universal interoperability. Extreme heterogeneity and spontaneous interactions are characteristics of today's complex distributed systems. To face the above challenges, we have introduced the notion of Emergent Middleware as part of the European CONNECT project. Emergent middleware ensures interoperation between two networked systems by combining message interoperability, i.e., the ability to interpret messages from/toward networked systems and behavioral interoperability, i.e., the ability to mediate the interaction protocols run by the communicating networked systems, under specified non-functional properties, e.g., reliability, performance and security. On-the-fly production of emergent middleware then relies on the following key enablers within the network: discovery of networked systems, learning of interaction protocols and synthesis of protocol mediators. In this talk, after an overview of the Emergent middleware principles, I will detail the proposed solution to automated mediator synthesis, which is based on ontology reasoning and constraint programming in order to infer mappings between components' interfaces automatically. These mappings guarantee semantic compatibility between the operations and data of the interfaces. Then, we analyse the behaviors of components in order to synthesise, if possible, a mediator that coordinates the computed mappings so as to make the components interact properly. Our approach is formally-grounded to ensure the correctness of the synthesized mediator. We demonstrate the validity of our approach by implementing the MICS (Mediator synthesIs to Connect componentS) tool and experimenting it with various real-world case studies.
