Adaptation of Web Services to the Context Based on Workflow: Approach for Self-Adaptation of Service-Oriented Architectures to the Context

Abstract

The emergence of Web services in the information space, as well as the advanced technology of SOA, give tremendous opportunities for users in an ambient space or distant, empowerment and organizations in various fields application, such as geolocation, E-learning, healthcare, digital government, etc.. In fact, Web services are a solution for the integration of distributed information systems, autonomous, heterogeneous and self-adaptable to the context. However, as Web services can evolve in a dynamic environment in a well-defined context and according to events automatically, such as time, temperature, location, authentication, etc.. We are interested in improving their SOA to empower the Web services to be self adaptive contexts. In this paper, we propose a new trend of self adaptability of Web services context. Then applying these requirements in the architecture of the platform of adaptability to context "WComp", by integrating the workflow. Our work is illustrated by a case study of authentication.

A new approach towards the self-adaptability of Service-Oriented Architectures to the context based on workflow

“…These studies have led to several implementations and case studies in different fields, such as, e-learning, smart house, RFID, etc... Result of these studies, we presented in our work [7] a proposal to an self-adaptable SOA when we've built a rules engine within WComp which can offer management rules that deal with business logic. Business logic can help in the development and optimization of these assemblies separating the events produced by the components defined in a WComp application.…”

The RQ-Tech methodology: a new paradigm for conceptualizing strategic enterprise architectures

“…In addition, the modern warfighter's environment is composed of a plethora of communication technologies. The standards that govern access to global information are in a state of flux as modern technology initiatives, such as Service Oriented Architectures (SOA), promise to transition the DoD to a more intelligent web structure using the Semantic Web (Felhi & Akaichi, 2012;W3C, 2004a). The root metaphor of industrial automation may no longer be representative of the military user's enterprise.…”
