A Survey of QoS-aware Web Service Composition Techniques

by Umar Shehu, Gregory Epiphaniou, Ghazanfar Ali Safdar
"... Web service composition can be briefly described as the process of aggregating services with disparate functionalities into a new composite service in order to meet increasingly complex needs of users. Service composition process has been accurate on dealing with services having disparate functional ..."

functionalities, however, over the years the number of web services in particular that exhibit similar functionalities and varying Quality of Service (QoS) has significantly increased. As such, the problem becomes how to select appropriate web services such that the QoS of the resulting composite service

Efficient QoS-aware Service Composition

by Mohammad Alrifai, Thomas Risse
"... Abstract. Web service composition requests are usually combined with end-toend QoS requirements, which are specified in terms of non-functional properties (e.g. response time, throughput and price). The goal of QoS-aware service composition is to find the best combination of services such that their ..."

A concept for QoS integration in web services

by M. Tian, A. Gramm, M. Nabulsi, H. Ritter, J. Schiller, T. Voigt - In 1st Web Services Quality Workshop (WQW2003) at WISE , 2003
"... Abstract: With the growing popularity of Web services, a general QoS support for Web services will play an important role for the success of this emerging technology. Unfortunately, current Web service environments do not offer comprehensive QoS support. In this paper, we present an approach that do ..."

that does not only enable the QoS integration in Web services, but also the selection of appropriate services based on QoS requirements regarding server and network performance as well as the mapping of QoS requirements onto the underlying QoS aware network at runtime. 1

User-Rating Based QoS Aware Approach for Selection of Updated Web Services to Web Service Composition

by K. Vivekan, S. Neelavathi, S. Subhashree, G. Kavitha, S. Kavitha
"... Abstract — The concept of dynamic composition of Web services has been given major importance in the recent years. While there are many systems available to select the services with the highest QoS score, very little thought has been given to the fact of constructing a model which takes in the user’ ..."

not only enable the QoS integration in Web services, but also the selection of appropriate services based on QoS requirements regarding server and network performance. Furthermore, we present how application requirements regarding communication QoS are mapped onto the underlying QoS aware network

J.Y.: Towards adaptive management of qos-aware service compositions

by Mariusz Momotko, Micha Gajewskił, André Ludwig, Ryszard Kowalczyk, Marek Kowalkiewicz, Jian Ying Zhang - nternational Journal on Multiagent and Grid Systems 4294 (2007) 637–650
"... Abstract. Service compositions enable users to realize their complex needs as a single request. Despite intensive research, especially in the area of business processes, web services and grids, an open and valid question is still how to manage service compositions in order to satisfy both functional ..."

functional and non-functional requirements as well as adapt to dynamic changes. In this paper we describe an approach towards adaptive management of QoS-aware service compositions. This approach integrates well known concepts and techniques and proposes various execution strategies based on dynamic selection

Variability Modeling and QoS Analysis of Web Services Orchestrations

by Ajay Kattepur, Sagar Sen, Benoit Baudry, Albert Benveniste, Claude Jard
"... Abstract—The ever-growing choice in diverse services is making service orchestration variability an essential aspect of a composite web service. Influence of this variation on the Quality of Service (QoS) of a composite service is critical and the focus of our work. In this paper, we present a metho ..."
