This paper presents a middleware framework to support the development of context-aware adaptive communication protocols, that can be reconfigured according not only to the local context, but also to the context of the remaining remote participants. The advantages of the framework are illustrated by using the concrete example of an adaptive group(More)
—The problem of self-optimization and adaptation in the context of customizable systems is becoming increasingly important with the emergence of complex software systems and unpredictable execution environments. Here, a general framework for automatically deciding on when and how to adapt a system whenever it deviates from the desired behavior is presented.(More)
There exists a growing class of distributed applications that require adaptive middleware services, i.e., services that are able to monitor changes in the execution environment and in the user's requirements, reacting to these changes by adapting their behaviour. This paper proposes modelling primitives that allow to describe the adaptation logic of(More)
Frameworks that support the implementation and execution of service compositions are a fundamental component of middleware in-frastructures that support the design of adaptive systems. This paper discusses the requirements imposed by adaptive middleware on service composition frameworks, and discusses how they have been addressed by previous work. As a(More)
