Smart environments and mobile computing systems increasingly converge, resulting in the emergence of pervasive computing environments. This development brings up new challenges that pertain to the variable availability and different mobility of heterogeneous services. Existing service interaction patterns in the area of service-oriented architecture (SOA)(More)
Modern telecommunication networks and classical roles of operators are subject to fundamental change. Many network operators are currently seeking for new sources to generate revenue by exposing network capabilities to 3rd party service providers. At the same time we can observe that applications on the World Wide Web (WWW) are becoming more mature in terms(More)
Context-awareness is a key requirement of human-centric computing systems. Applications may ease user interaction or even anticipate the behavior of the user when utilizing information about the current context. The pervasive provision of context data represents a major challenge in this scope. For that reason we introduce an approach for gathering,(More)
Pervasive Gaming, mobile gaming applications interweaved into the real world, is an emerging field for context-aware multimedia applications. Mobile multimedia applications are fostered by the improvement of hardware technology and the emergence of new devices with sufficient networking and processing capabilities. However, these extending possibilities(More)
Service-oriented computing paradigms have considerably enhanced support for dynamic in modern computing environments by providing loosely coupled interactions between components. The key attainment is the ability to perform a late binding of service compositions, i.e., an allocation of actual services to service place holders during run-time. However, this(More)
This paper presents the networking framework as conceived within the European project BIONETS. The case for such a framework comes from the idea of a ldquoDisappearing Networkrdquo paradigm. In the disappearing network, the network ceases to exist as an independent entity and becomes an appendix of the distributed services running on user devices. The(More)
The view on applications in large-scale open systems shifted to a service-oriented perspective, where each functional feature forming an application is regarded as service. The services which constitute an application can be physically spread over different network nodes and can be even provided by different administrative entities. According to the vision(More)
enable context-aware applications is a topic often discussed in current research. However, related approaches are not able to cope with the unknown and dynamically changing nature often found in ad-hoc peer-to-peer environments. In this paper, we propose a flexible means of gathering, interpreting, and providing context information in a distributed manner.(More)
