EDITORIAL PREFACE:

Web Services in Access, Control, and Pricing

Liang-Jie Zhang, Editor-in-Chief, IBM, T.J. Watson Research Center, USA

This issue of the International Journal of Web Services research (JWSR) collects five papers on various topics of Web services. Topics include Mobile Ad hoc NETworks (MANETs), a Web services-oriented access-control model, a suite of automated software tools to facilitate the construction of OWL-S specifications, an auction-based pricing model for Web service providers, and a Quality of Services (QoS) Management Architecture to support dynamic end-toend QoS requests and analyses in Web-service oriented architectures.

RESEARCH PAPERS

PAPER ONE:

“Supporting Predictable Service Provision in MANETs Via Context-Aware Session Management”

Radu Handorean, Washington University in St. Louis, USA
Rohan Sen, Washington University in St. Louis, USA
Gregory Hackmann, Washington University in St. Louis, USA
Gruia-Catalin Roman, Washington University in St. Louis, USA

The increasing ubiquity of wireless mobile devices is promoting unprecedented levels of electronic collaboration among devices interoperating to achieve a common goal. Issues related to host interoperability are addressed partially by the principles of the service-oriented computing paradigm. However, certain technical concerns relating to predictable interactions among hosts in mobile ad hoc networks (MANETs) have not yet received much attention. This article introduces “follow-me sessions,” where interactions occur between a client and a service, rather than a specific service provider. A client, thus, may exploit several service providers during the course of its interaction with a given service. This redundancy mitigates the effects of mobility-induced disconnections, thereby facilitating reliable communication. This paper covers the architecture and implementation of a middleware that supports follow-me sessions and shows how this middleware mitigates issues related to proxy-based service-oriented architectures in mobile ad hoc networks.

PAPER TWO:

“An Adaptive Access Control Model for Web Services”

Elisa Bertino, Purdue University, USA
Anna C. Squicciarini, Purdue University, USA
Lorenzo Martino, Purdue University, USA
Federica Paci, University of Milano, Italy

This paper presents an innovative access control model, referred to as Web service Access Control Version 1 (Ws-AC1), specifically tailored to Web services. The most distinguishing features of this model are the flexible granularity in protection objects and negotiation capabilities. Formal definitions underlying the model and the relevant algorithms, such as the access control algorithm are presented. An encoding of the model in the Web Services Description Language (WSDL) standard for which a required extension is developed to support Ws-AC1 is also presented.

PAPER THREE:

“Facilitating the Specification of Semantic Web Services Using Model-Driven Development”

Gerald C. Gannod, Miami University (OH), USA
John T. E. Timm, Arizona State University - Tempe Campus, USA
Raynette J. Brodie, Arizona State University - Tempe Campus, USA

The semantic Web promises automated invocation, discovery, and composition of Web services by enhancing services with semantic descriptions. An upper ontology for Web services called OWL-S has been created to provide a mechanism for describing service semantics in a standard, well-defined manner. Unfortunately, the learning curve for semantic-rich description languages such as OWL-S can be steep, especially given the current state of tool support for the language. This paper describes a suite of automated software tools the authors developed to facilitate the construction of OWL-S specifications. This paper describes the tools and demonstrates how the use of lightweight interactive tools facilitates creation of OWL-S specifications.

PAPER
FOUR:

“Auction-Based Pricing Model for Web Service Providers”

Jia Zhang, Northern Illinois University, USA
Ning Zhang, Cornell University, USA
Liang-Jie Zhang, IBM T.J. Watson Research Center, USA

Applying auctions to Web services selection and invocation calls for examination due to the unique features of Web services, such as interoperable machine-to-machine interactions and re-enterable bargaining services. In this paper, the authors propose a formal model for Web services-based auctions. Examining a one-sided sealed auction type, they prove mathematically that service requestors’ risk preferences could lead to pricing strategies with a higher profit for service providers. A basic service requestor risk preference elicitation algorithm and a historical data-based service requestor risk preference prediction model are proposed.

PAPER FIVE:

“A Service-Oriented Composition Framework with QoS Management”

Casey K. Fung, Boeing Phantom Works, USA
Patrick C. K. Hung, University of Ontario Institute of Technology, Canada
Richard C. Linger, Carnegie Mellon University, USA
Guijun Wang, Boeing Phantom Works, USA
Gwendolyn H. Walton, Carnegie Mellon University, USA

Quality of Services (QoS) management in compositions of services requires careful consideration of QoS characteristics of the services and effective QoS management in their execution. This paper describes an approach to implementation of QoS management in compositions of Web services in the context of Computational Quality Attributes and Service Level Agreements. Building on prior research work of others in the use of Message Detail Records, this paper integrates the results from several research threads to propose a QoS Management Architecture to support dynamic processing of service- and flow-level quality attributes to support QoS requests and analyses in Web-service-oriented architectures. The study of QoS management in a Web service composition framework was motivated by the evolution of the composition framework for a toolkit for integration and experimentation of distributed system applications. A message tracking model is proposed for supporting QoS end-to-end management by applying the Computational Quality Attribute (CQA) concepts of Flow-Service-Quality engineering. Quality attributes are defined, computed and acted upon as dynamic characteristics of systems, with values constantly changing in operation. A CQA provision is illustrated, with a simple Web Services travel reservation example. The example is elaborated to illustrate QoS end-to-end management using the Simple Object Access Protocol (SOAP) message tracking model.

CALL FOR PAPERS

Mission of JWSR:

Web Services are among the most important emerging technologies in the e-business, computer software and communication industries. The Web Services technologies will redefine the way that companies do business and exchange information in the twenty-first century. They will enhance business efficiency by enabling dynamic provisioning of resources from a pool of distributed resources. Due to the importance of the field, there is a significant amount of ongoing research in the areas. In a parallel effort, standardization organizations are actively developing standards for Web Services. The Web Services are creating what will become one of the most significant industries of the new century. The International Journal of Web Services Research is designed to be a valuable resource providing leading technologies, development, ideas, and trends to an international readership of researchers and engineers in the field of Web Services.
