AICT/SAPIR/ELETE - A Service-Oriented Architecture framework for mobile Services
Advanced Industrial Conference on Telecommunications Service Assurance with Partial and Intermittent Resources Conference E-Learning on Telecommunicat, 2005Co-Authors: Van Thanh, Ivar JørstadAbstract:Service-Oriented Architectures and Service-Oriented computing are the most recent approaches aimed at facilitating the design and development of applications on distributed systems. The paper investigates how the construction of mobile Services can benefit from the Service-Oriented paradigm. The paper provides a presentation of the Service-Oriented Architecture. A general discussion of equivalence between Service components is then undertaken, in order to enable an analysis of Service-Oriented Architectures for mobile Services. The paper proceeds with a mapping of existing mobile Services on Service-Oriented Architectures. The requirements of mobile Services, which must be taken into consideration in the Service-Oriented Architecture, are identified from a generic model of mobile Services. A Service-Oriented Architecture framework supporting mobile Services is proposed.

A Service Oriented Architecture Framework for Collaborative Services
14th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprise (WETICE'05), 2005Co-Authors: Ivar Jørstad, Schahram DustdarAbstract:The demand for flexible, efficient and user-friendly collaborative Services is becoming more and more urgent as the competition in the current market-Oriented arena is getting more intense and fiercer. Enterprises have to be more dynamic in terms of of collaboration with partners and even competitors. The Service Oriented Architecture is a promising distributed computing paradigm offering solutions that are extendible, flexible and compatible with legacy systems. This paper proposes and investigates the use of SOA in the construction of collaborative Services. The paper starts with a short introduction of the Service Oriented Architecture and then gives a description of collaborative Services. A generic model of a collaborative Service is analysed to identify the basic collaborative functions. A Service Oriented Architecture Framework for collaborative Service is presented.

An Overview of Service Composition in Service Oriented Architecture
Mathematical Models and Methods in Applied Sciences, 2018Co-Authors: Faten HamadAbstract:Service Oriented Architecture (SOA) is a form of software design in which application component supply Services to other components through a network communication protocol, it has many Services that can transfer small data with communication channels or additional Services which bring into a relationship that ensure efficiency of Service activities, SOA simplify the structure of loosely coupled applicable applications and enable contribution for enterprise working of Services together. In order to assure the effectiveness of Service Oriented Architecture we have to confirm Service composition which is the collection of Services together in order to perform a specific function which can be used in Service Oriented Architecture. In this paper we proposed a Service composition in SOA, it is present Service composition with various techniques used for composing Services and provided a comparison between them.

Service Composition in Service Oriented Architecture: A Survey
Mathematical Models and Methods in Applied Sciences, 2018Co-Authors: Fatima Aladwan, Ahmad Alzghoul, Hussam N. Fakhouri, Israa AlzghoulAbstract:AbstractService-Oriented Architecture (SOA) is a modular approach to software development based on the use of distributed, loose coupling replaceable components equipped with standardized interfaces for interaction over standardized protocols Component interfaces in a Service-Oriented Architecture encapsulate the implementation details (operating system, platform, programming language) from the rest of the components, thereby enabling the combination and reuse of components to build complex distributed software packages, ensuring independence from the platforms and development tools used, facilitating scalability and manageability of the systems being created. In this paper we introduce a Service composition in Service Oriented Architecture, it is present Service composition with different approach used for composing Services and provided.

MODELSWARD (Revised Selected Papers) - Identifying Performance Objectives to Guide Service Oriented Architecture Layers
Communications in Computer and Information Science, 2017Co-Authors: Tehreem Masood, Chantal Cherifi, Néjib MoallaAbstract:Service Oriented Architecture is emerging as a powerful paradigm for organizations that need to integrate their applications within and across organizational boundaries. Organizations need to take decisions more quickly and need to change those decisions dynamicaly. Delivering an adequate level of performance is a critical and significant challenge that requires monitoring along the different layers of Service Oriented Architecture. Current monitoring systems are designed to support specific layers but do not fulfil the requirements of all the layers of Service Oriented Architecture. Ontologies on the semantic web standardize and formalize the concepts and store domain knowledge for effective decision making. In this paper, we propose performance monitoring framework for various layers of Service Oriented Architecture. It integrates various ontologies to monitor the performance at the Service Oriented layers in order to ensure their sustainability. We design a Service Performance Ontology that captures all the information about the Service domain. Along with that we design ontologies for ensuring performance at Service level, binding level, composition level and server level. We conduct a performance evaluation over real web Services using suitable estimators for response time, delay, loss and more.

Service Oriented Architecture-Risks and Remedies
Social Science Research Network, 2011Co-Authors: Deepa V. Jose, Smitha VinodAbstract:SOA (Service Oriented Architecture) is not just Architecture of Services seen from a technology perspective, but the policies, practices, and frameworks by which we ensure the right Services are provided and consumed. This paper titled Service Oriented Architecture-Risks and Remedies is the outcome of the efforts to study Service Oriented Architecture, its efficiency and drawbacks. Some methods to tackle the problems faced by SOA are also briefed.
