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

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

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?

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.
