چکیده

Service oriented computing provides suitable means to technically support distributed collaboration of heterogeneous devices such as in mobile environments. However, wireless communication links are unstable. When supporting collaboration in such environments, failures have to be optimistically coped with in order to still provide suitable correctness guarantees and avoid inconsistent system states. In this paper, we explore transactional properties of services in order to reasonably integrate transactional coordination with composition of services in mobile networks and provide suitable correctness guarantees.

Flexible Workflows to Support Transactional Service Composition in Mobile Environments

Service oriented computing provides suitable means to technically support distributed collaboration of heterogeneous devices, for example those present in mobile environments. E.g., many applications are built on composite Web-Services. However, when executing these applications in dynamic environments, failures of participating entities have to be optimistically coped with, in order to avoid i...

Reliable Execution Based on CPN and Skyline Optimization for Web Service Composition

With development of SOA, the complex problem can be solved by combining available individual services and ordering them to best suit user's requirements. Web services composition is widely used in business environment. With the features of inherent autonomy and heterogeneity for component web services, it is difficult to predict the behavior of the overall composite service. Therefore, transact...

Multi-Level Modeling of Web Service Compositions with Transactional Properties

Web services have become popular as a vehicle for the design, integration, composition, reuse, and deployment of distributed and heterogeneous software. However, although industry standards for the description, composition, and orchestration of Web services have been under development, their conceptual underpinnings are not fully understood. Conceptual models for service specification are rare,...

Context-based transactional service selection approach for service composition

Building applications dynamically from individual services offered by different organizations is one of the opportunities that Service-oriented Architecture (SoA) provides. With increasing number of providers, there is a choice among several functionally equivalent services resulting in a need to select the most appropriate ones in terms of Quality of Service (QoS) and transactional properties....

Service Selection of Ensuring Transactional Reliability and QoS for Web Service Composition

Service-Oriented Architecture SOA provides a flexible framework of service composition. Using standard-based protocols, composite service can be constructed by integrating component services independently. As component services are developed by different organization and offer diverse transactional properties and QoS characteristics, it is a challenging problem how to select suitable component ...
