A Multiagent Approach To Web Service Composition Based On TROPOS Methodology

Abstract

Web services are nowadays providing users with a diverse range of services. They are mostly delivered through web applications. It is often the case that a single atomic web service cannot fulfill the demands of users. Rather, many simple atomic web services may have to be composed and form a complex one in order to handle users' growing requests properly. Regarding the overall structure of web services as passive software components, they might fail to succeed properly, facing new types of requests. Recently, the concept of multiagent systems inspired many solutions in various research fields. In the web service composition domain, using smart agents so as to composite web services appropriately, leads to a complex, dynamic, and flexible service that meets different quality metrics altogether. In this study, a multiagent-based solution to web service composition is proposed using the “TROPOS” methodology that handles incoming requests based on constructing task dependency graphs.
