Energy-Aware Autonomic Resource Allocation in Multitier Virtualized Environments
With the increase of energy consumption associated with IT infrastructures, energy management is becoming a priority in the design and operation of complex service-based systems. At the same time, service providers need to comply with Service Level ...
Dynamic Authentication for Cross-Realm SOA-Based Business Processes
Modern distributed applications are embedding an increasing degree of dynamism, from dynamic supply-chain management, enterprise federations, and virtual collaborations to dynamic resource acquisitions and service interactions across organizations. Such ...
Bootstrapping Ontologies for Web Services
Ontologies have become the de-facto modeling tool of choice, employed in many applications and prominently in the semantic web. Nevertheless, ontology construction remains a daunting task. Ontological bootstrapping, which aims at automatically ...
A Dataflow-Based Scientific Workflow Composition Framework
Scientific workflow has recently become an enabling technology to automate and speed up the scientific discovery process. Although several scientific workflow management systems (SWFMSs) have been developed, a formal scientific workflow composition ...
Using Rules and Data Dependencies for the Recovery of Concurrent Processes in a Service-Oriented Environment
This paper presents a recovery algorithm for service execution failure in the context of concurrent process execution. The recovery algorithm was specifically designed to support a rule-based approach to user-defined correctness in execution ...
Reducing Adapter Synthesis to Controller Synthesis
Service-oriented computing aims to create complex systems by composing less-complex systems, called services. Since services can be developed independently, the integration of services requires an adaptation mechanism for bridging any incompatibilities. ...
ubiSOAP: A Service-Oriented Middleware for Ubiquitous Networking
The computing and networking capacities of today's wireless portable devices allow for ubiquitous services, which are seamlessly networked. Indeed, wireless handheld devices now embed the necessary resources to act as both service clients and providers. ...
A Proxy-Based Architecture for Dynamic Discovery and Invocation of Web Services from Mobile Devices
Mobile devices are getting more pervasive, and it is becoming increasingly necessary to integrate web services into applications that run on these devices. We introduce a novel approach for dynamically invoking web service methods from mobile devices ...
Collaborative Testing of Web Services
Software testers are confronted with great challenges in testing Web Services (WS) especially when integrating to services owned by other vendors. They must deal with the diversity of implementation techniques used by the other services and to meet a ...
RLM: A General Model for Trust Representation and Aggregation
Reputation-based trust systems provide important capability in open and service-oriented computing environments. Most existing trust models fail to assess the variance of a reputation prediction. Moreover, the summation method, widely used for ...
