Security Aware Service Composition
Security assurance of Service-Based Systems (SBS) is a necessity and a key challenge in Service Oriented Computing. Several approaches have been introduced in order to take care of the security aspect of SBSs, from the design to the implementation stages. Such solutions, however, require expertise …

Semantics-based automatic geospatial service composition
… based on the reuse of existing components or services, technical complexity and semantic challenges constitute barriers to ensuring a successful and wide reuse of components and services. In the geospatial application domain, the barriers are self-evident due to heterogeneous geographic data, …

Efficient Adaptive Multi-Granularity Service Composition
Despite the tremendous benefits of the dynamic, service-oriented approach to build composite applications, it also brings great challenges. In particular, the run-time selection of the most suitable services for an application in a timely manner is not trivial, since many providers could be …

A Compositional Semantic Theory for Service Composition
Service Composition refers to a popular modern software paradigm for building applications by combining distributed reactive components using the World-Wide-Web as the medium. The approach is characterised by the use of standardised protocols, languages and representations such as XML, which …

A semantic framework for event-driven service composition
Service Oriented Architecture (SOA) has become a popular paradigm for designing distributed systems where loosely coupled services (i.e. computational entities) can be integrated seamlessly to provide complex composite services. Key challenges are discovery of the required services using their …

SMART DATA-INTENSIVE SERVICE COMPOSITION IN CLOUD-EDGE CONTINUUM
La proliferazione di dispositivi IoT, dell’analisi in tempo reale e di applicazioni data-intensive ha messo in discussione l’adeguatezza del cloud computing tradizionale, che, pur offrendo elevata scalabilità, spesso non riesce a soddisfare i requisiti stringenti di latenza, banda e affidabilità …

Towards Provably Correct Services: Automated Service Composition Via Supervisory Control Synthesis
Service-oriented computing (SOC) is a distributed computing paradigm that is revolutionizing the development of software systems. Service-oriented architecture (SOA) provides a framework for realizing and implementing SOC. A Web service is a key concept for developing SOA applications that allows …

Trust-Based Service Management for Service-Oriented Mobile Ad Hoc Networks and Its Application to Service Composition and Task Assignment with Multi-Objective Optimization Goals
… networks (MANETs) now migrate into a new era of service-oriented MANETs wherein a node can provide and receive service from other nodes it encounters and interacts with. This dissertation research concerns trust management and its applications for service-oriented MANETs to answer the challenges …

A Proactive Adaptation Framework for Composite Web Services
Service orientation is a design paradigm consisting of a set of principles governed by a service-oriented architecture (SOA) to support the creation of software systems as a composition of interoperable services. The ability to effectively compose services is not a trivial task due to the dynamic …

A Compositional Framework for the Specification, Verification and Runtime Validation of Reactive Web Services
… widely researched themes in the domain of Web services. Current efforts however consider only "static” aspects of service behaviours. XML-based standards/Ontologies for services are limited to specifying interface predicates as precondition, effect or postcondition. These properties do not …

Investigations into the model driven design of distribution patterns for web service compositions
… Traditional approaches to development of Web service compositions exhibit a number of Issues Firstly, Web service composition development is often ad-hoc and requires considerable low level coding effort for realisatlon Such systems often exhibit fixed architectures, making maintenance …

End-to-end security in service-oriented architecture
<p>A service-oriented architecture (SOA)-based application is composed of a number of distributed and loosely-coupled web services, which are orchestrated to accomplish a more complex functionality. Any of these web services is able to invoke other web services to offload part of its functionality. …
