Abstract
The environments of pervasive computing are open and dynamic. In order to ensure the adaptation of the service composition and the dynamic handling of the context in such environments, we suggest a new approach based on the taking into account information of context to adapt the process of composing services. Although there exist many composition norms that have been suggested, such as BPML and BPEL4WS, these norms are somewhat limited in terms of the dynamic adaptation of the service composition during the execution. In this paper, we present an approach that takes into account at the same time the user’s context and the services, with integrating them in the service description language WSDL and in the composition process BPEL. The suggested extensions, known as A-WSDL and A-BPEL, permit us to describe the adaptations capable of bearing the service, the composition of services and the dynamic handling of context.
