MagEl: A Magneto-Electric Effect-Inspired Approach for Web Service Composition
Résumé
Web service composition is the art of combining multiple platform independent and modular pieces of software with varied configurations, to achieve an efficient solution for a complex business process. Though Web service composition has been an important area of research in the past decade, the search for procuring an optimal configuration of Web services to execute a business process remains a challenge. The issue is aggravated by the fact that the ‘Future Internet’ is expected to house billions of services, with thousands offering the same functionality. In this context, maintaining an operational and solid set of Web service configurations will be a challenging task. Moreover, a centralized solution for Web service composition in the Future Internet scenario would be another issue. In this paper, we present a technique inspired from Electro-Magnetism in physics to create an environment which facilitates the selection of a service from a set of similar services. The
proposed model achieves service composition in a decentralized environment without involving a centralized orchestrator. To validate the proposed technique in-silico experiments were conducted whose results demonstrate good performance in terms of completion time and load balancing. Further, the proposed technique is validated in-house (within our institute’s intranet and with real users) by deploying real world Web services on decentralized nodes. The results obtained via simulation are verified through a prototype based on the proposed model. We present, discuss and compare the effectiveness of the proposed work in the results section.
