“…The logical description of a mashup instance is an important artifact, which is used in later phases to suggest implementation possibilities or to exchange components at run-time, especially in telco-specific scenarios such as roaming. We suggest using RDF-based description languages and dedicated knowledge models to enable automatic composition and context adaption tasks [23].…”

Abstract. In this paper we present our approach to integrate telco services into enterprise mashup applications. We show how cross-network integration and multi-user-oriented mashup concept support execution and orchestration of business processes. We identify the main classes of telco services and provide a reference architecture for telco-enabled mashup applications. Finally, we describe our approach for systematic integration process and give an outlook into our further research.

“…An important feature of COIVA is the decoupling of modules to support scalability; this method also provides a way to anticipate future changes. For example, our approach separates the context model from behavioral mechanisms; Fortier et al 54 and Lu et al 55 studied in detail this requirement for context‐aware architectures. In general, the separation of the knowledge base from the inference engine is desirable from at least two standpoints.…”

This paper exploits semantics to apply context in run‐time adaptation, particularly for services in a user‐centered smart environment. Context‐sensitive services are usually focused on their own information without interoperation pretensions. It is necessary to enable common context models and systems in order to make context‐aware applications interoperable. Moreover, context management systems need to implement mechanisms to support the dynamic behavior of the users and their surroundings, including techniques to adapt the model to their future needs, to maintain the context information at run‐time and to be interoperable with external context models. By adapting web semantic technologies we can enable smarter and more proactive operation of context management systems. Copyright © 2010 John Wiley & Sons, Ltd.

With the increasing popularity of smartphones and netbooks, more and more applications are developed for the mobile platform. Notwithstanding the recent advances in mobile hardware, most mobile devices still lack sufficient resources (e.g. CPU power, memory) to execute complex multimedia applications such as augmented reality. Application developers also have difficulties to cope with the changing device context (e.g. network connectivity, remaining battery life) and the many different hardware platforms and operating systems to run applications on. Therefore, we introduce the concept where the developer can provide different configurations of an application, each having different resource requirements and a different quality offered to the end user. The middleware framework presented in this paper will select and deploy the configuration offering the best quality possible for the current connectivity and available resources. As these change over time, the framework will dynamically adapt the configuration and deployment at runtime, enhancing the quality by offloading parts of the application when a remote server is discovered, or gracefully degrading the quality when the network connection is lost. Based on experimental results on the augmented reality use case the performance and effectiveness of our middleware has been characterized in different scenarios.
