Genetic-based approach for ATS and SLA-aware web services composition

Résumé

Composite applications leveraging several functionalities offered by Web services are today the underpinnings of enterprise computing. There are two kinds of requirements of web service composition: QoS requirements and transactional requirements. The QoS requirements are recorded in service-level agreements (SLAs) contract. The transactional requirements are expressed by designers as a set of accepted termination states (ATS). In this paper, we propose a novel selection and composition approach called ATS and SLA-aware Web services composition (WSC). Our approach aims at finding composite service compliant with ATS and better satisfying the SLA contract. As the ATS and SLA-aware WSC is NP-hard problem, an efficient algorithm is required. This work adopts genetic algorithm to deal with combinatorial problem
