Composition and Run-time Adaptation of Mismatching Behavioural Interfaces

Abstract: Reuse of software entities such as components or Web services raise composition issues since, most of the time, they present mismatches in their interfaces. These mismatches may appear at different interoperability levels: signature, behaviour, quality of service and semantics. The behavioural level is crucial and behavioural mismatches must all be corrected, although this is a difficult task. So far, most adaptation approaches which deal with behavioural mismatches work on a fixed description of components where all ports involved in their interfaces are known at design-time. Here, we focus on systems in which composition is affected by run-time behaviour of the system. This is the case in pervasive systems where a client interacts with a specific service by using new communication channels dynamically created. These are of special interest to allow private interaction between several entities. In this article, we define a behavioural model inspired by the -calculus to speci...
