Selection of the best composite web service based on quality of service

Abstract

The paper proposes a general framework to composite Web services selection based on multicriteria evaluation. The proposed framework extends the Web services architecture by adding, in the registry, a new Multicriteria Evaluation Component (MEC) devoted to multicriteria evaluation. This additional component takes as input a set of composite Web services and a set of evaluation criteria and generates a set of recommended composite Web services. In addition to the description of the conceptual architecture of the formwork, the paper also proposes solutions to construct and evaluate composite web services. In order to show the feasibility of the proposed architecture, we have developed a prototype based on the open source jUDDI registry.
