Developing applications with intelligent context access capabilities is challenged by the difficulty of obtaining advanced context information. The complexity of the logic required for processing context information adds another barrier for developing advanced context-aware applications. In this research paper, we propose a solution that allows context information sharing and extension toward the...
One of the main concerns of Cloud storage solutions is to offer the availability to the end user. Thus, addressing the mobility needs and device's variety has emerged as a major challenge. At first, data should be synchronized automatically and continuously when the user moves from one equipment to another. Secondly, the Cloud service should offer to the owner the possibility to share data with specific...
The European VPH-Share project develops a comprehensive service framework with the objective of sharing clinical data, information, models and workflows focusing on the analysis of the human physiopathology within the Virtual Physiological Human (VPH) community. The project envisions an extensive and dynamic data infrastructure built on top of a secure hybrid Cloud environment. This paper presents...
With the advance and pervasion of mobile devices and fast growth of high speed Internet connections, our life is inevitable to be changed. These devices are combined with sensors such as Radio Frequency Identification (RFID) operating on wireless infrastructure to form a wireless sensor networks (WSN) which could facilitate our life in many ways. We would expect a shopping experience in which customers...
The creating of reusable mobile solutions is influenced by many factors. The platforms are arbitrary, the target audience can be new to mobile software, and the devices are not always online and restricted in their computational capabilities. This paper presents an archetype pattern- and REST-driven approach for building customizable, flexible, and efficient mobile business applications. Furthermore,...
The emergence of the Internet has changed the nature of face-to-face towards online interactions. This leads to the concept of virtual interoperation such as Web Services, Grid, and Cloud Computing. Since existing security mechanisms are insufficient to cover the diversity of workflow application domains, trust is considered as an adaptive, high-level abstraction, and platform-independent solution...
Service Oriented Infrastructures including Grid and Cloud Computing are technologies in a critical transition to wider adoption by business. Their use may enable enterprises to achieve optimal IT utilization, including sharing re-sources and services across-enterprises and on-demand utilization of those made available by business partners over the network. This paper presents a selection of common...
Much work is underway within the broad next generation technologies community on issues associated with the development of services to foster collaboration via the integration of distributed and heterogeneous data systems and technologies. Various technology-driven paradigms have emerged, including Web Services, Web 2.0, Pervasive, Grids and Cloud Computing. Recently, some new paradigms have emerged,...
In Cloud service composition, collaboration between brokers and service providers is essential to promptly satisfy incoming Cloud consumer requirements. These requirements should be mapped to Cloud resources, which are accessed via web services, in an automated manner. However, distributed and constantly changing Cloud-computing environments pose new challenges to automated service composition such...
Traditional Learning Management Systems (LMS) failed in providing pervasive and personal services since lacking flexibility and adaptivity. This paper addresses the problems in existing LMSs and reviews related technologies in improving interoperability, reusability, flexibility and cost efficiency, followed by proposing a new framework design using service-Oriented architecture.
Services are expected to be a promising way for people to use information and computing resources in the emerging ubiquitous network society. In this study, we propose a metaphoric concept called flowable service. It is defined as a logical stream that organizes and provides circumjacent services in such a way that they are perceived by individuals as those naturally embedded in their surrounding...
Current service cloud models can be easily seen as application-centered: they provide an access point to services and artifacts but, including them as separate resources, they do not offer a unified and cross-application perspective on users' activities. As an answer to this issue, we present a user-centered cloud model which, by enabling services to synchronize on a unified context, enhances users'...
The increasing processing power, storage and support of multiple network interfaces are promising the mobile devices to host services and participate in service discovery network. A few efforts have been taken to facilitate provisioning mobile Web services. However they have not addressed the issue about how to host heavy-duty services on mobile devices with limited computing resources in terms of...
We observe two of the recent trends in information technology. Cloud Computing (CC) is widely accepted as an effective reuse paradigm. Mobile Computing with Mobile Internet Device (MID) such as iPhones and Android devices becomes a convenient alternative to personal computers by integrating mobility, communication, software functionality, and entertainment. Due to the resource limitations of MIDs,...
Cloud computing is an emerging computing paradigm. It aims to share data, calculations, and services transparently among users of a massive grid. Although the industry has started selling cloud-computing products, the software engineering infrastructure and application model are still unclear. In this paper, we compare cloud computing with service-oriented computing and pervasive computing. Both the...
Cloud computing is an emerging computing paradigm. It aims to share data, calculations, and services transparently among users of a massive grid. Although the industry has started selling cloud-computing products, research challenges in various areas, such as UI design, task decomposition, task distribution, and task coordination, are still unclear. Therefore, we study the methods to reason and model...
