Adaptation of Web services to the context based on workflow: Approach for self-adaptation of service-oriented architectures to the context

摘要

The emergence of Web services in the information space, as well as theadvanced technology of SOA, give tremendous opportunities for users in anambient space or distant, empowerment and organizations in various fieldsapplication, such as geolocation, E-learning, healthcare, digital government,etc.. In fact, Web services are a solution for the integration of distributedinformation systems, autonomous, heterogeneous and self-adaptable to thecontext. However, as Web services can evolve in a dynamic environment in awell-defined context and according to events automatically, such as time,temperature, location, authentication, etc.. We are interested in improvingtheir SOA to empower the Web services to be self adaptive contexts. In thispaper, we propose a new trend of self adaptability of Web services context.Then applying these requirements in the architecture of the platform ofadaptability to context WComp, by integrating the workflow. Our work isillustrated by a case study of authentication.
