Abstract
The increasing number of Web service providers throughout the globe, have produced numerous Web services providing the same or similar functionality. This necessitates the use of tools and techniques to search the suitable services available over the Web. The effective dynamic Web service selection mechanism is a challenging problem as the requester is involved in the selection having wide variety of requirements. Quality of Service (QoS) is one of the decisive factor in selecting the desired Web service for the requester. This paper reviews various QoS based Web service selection mechanisms and architectures which facilitate qualitatively optimal selection. The authors classify various selection mechanisms based on the nature of QoS requirements used for the selection. The paper also compares the performance of QoS based selection mechanisms with respect to a set of evaluation criterion.
