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)=20
collects five papers on various topics of Web services. Topics include=20
Mobile Ad hoc NETworks (MANETs), a Web services-oriented access-control=20
model, a suite of automated software tools to facilitate the construction=20
of OWL-S specifications, an auction-based pricing model for Web service=20
providers, and a Quality of Services (QoS) Management Architecture to=20
support dynamic end-toend QoS requests and analyses in Web-service=20
oriented architectures.

RESEARCH PAPERS

PAPER ONE:=20

?Supporting Predictable Service Provision in MANETs Via Context-Aware=20
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=20
unprecedented levels of electronic collaboration among devices=20
interoperating to achieve a common goal. Issues related to host=20
interoperability are addressed partially by the principles of the=20
service-oriented computing paradigm. However, certain technical concerns=20
relating to predictable interactions among hosts in mobile ad hoc networks =

(MANETs) have not yet received much attention. This article introduces=20
?follow-me sessions,? where interactions occur between a client and a=20
service, rather than a specific service provider. A client, thus, may=20
exploit several service providers during the course of its interaction=20
with a given service. This redundancy mitigates the effects of=20
mobility-induced disconnections, thereby facilitating reliable=20
communication. This paper covers the architecture and implementation of a=20
middleware that supports follow-me sessions and shows how this middleware=20
mitigates issues related to proxy-based service-oriented architectures in=20
mobile ad hoc networks.

PAPER TWO:=20

?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=20
services. The most distinguishing features of this model are the flexible=20
granularity in protection objects and negotiation capabilities. Formal=20
definitions underlying the model and the relevant algorithms, such as the=20
access control algorithm are presented. An encoding of the model in the=20
Web Services Description Language (WSDL) standard for which a required=20
extension is developed to support Ws-AC1 is also presented.

PAPER THREE:=20

?Facilitating the Specification of Semantic Web Services Using=20
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=20
mechanism for describing service semantics in a standard, well-defined=20
manner. Unfortunately, the learning curve for semantic-rich description=20
languages such as OWL-S can be steep, especially given the current state=20
of tool support for the language. This paper describes a suite of=20
automated software tools the authors developed to facilitate the=20
construction of OWL-S specifications. This paper describes the tools and=20
demonstrates how the use of lightweight interactive tools facilitates=20
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=20
examination due to the unique features of Web services, such as=20
interoperable machine-to-machine interactions and re-enterable bargaining=20
services. In this paper, the authors propose a formal model for Web=20
services-based auctions. Examining a one-sided sealed auction type, they=20
prove mathematically that service requestors? risk preferences could lead=20
to pricing strategies with a higher profit for service providers. A basic=20
service requestor risk preference elicitation algorithm and a historical=20
data-based service requestor risk preference prediction model are=20
proposed.

PAPER FIVE:=20

?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=20
careful consideration of QoS characteristics of the services and effective =

QoS management in their execution. This paper describes an approach to=20
implementation of QoS management in compositions of Web services in the=20
context of Computational Quality Attributes and Service Level Agreements.=20
Building on prior research work of others in the use of Message Detail=20
Records, this paper integrates the results from several research threads=20
to propose a QoS Management Architecture to support dynamic processing of=20
service- and flow-level quality attributes to support QoS requests and=20
analyses in Web-service-oriented architectures. The study of QoS=20
management in a Web service composition framework was motivated by the=20
evolution of the composition framework for a toolkit for integration and=20
experimentation of distributed system applications. A message tracking=20
model is proposed for supporting QoS end-to-end management by applying the =

Computational Quality Attribute (CQA) concepts of Flow-Service-Quality=20
engineering. Quality attributes are defined, computed and acted upon as=20
dynamic characteristics of systems, with values constantly changing in=20
operation. A CQA provision is illustrated, with a simple Web Services=20
travel reservation example. The example is elaborated to illustrate QoS=20
end-to-end management using the Simple Object Access Protocol (SOAP)=20
message tracking model.
