In the last couple of years, huge research effort has been spent focusing on the realization of wireless sensor networks, especially in the area of radio interface efficiency , power consumption, ad-hoc networking, routing etc. In this paper we would like to focus on how sensors/ actuators and sensor networks can be integrated into the Internet and(More)
(WG2) has been active in the area of service architectures for future wireless systems. The vision of I-centric communication has been developed putting the individual user (" I ") in the center of service provisioning rather than offering inflexible services that are unaware of actual customer needs or situations. I-centric systems relieve the user of(More)
The convergence of embedded systems and wireless communication enables interconnection of electronic devices to render control and provide information to the user. Offices, apartments, and public spaces are or in near future will be able to deliver information and services to their occupants ranging from instant Internet access to configuration and control(More)
In the last two years a variety of concepts for service integration and corresponding systems have gained momentum. On the one hand, they aim for the interworking and integration of classical telecommunications and data communications services, such as telephony, voicemail, fax, e-mail, paging, etc. On the other hand, they are fo-cusing on universal service(More)
Quadruple play can be understood as the provisioning of high-speed voice, video (live broadcast or on demand services, such as video on demand), and data services over broadband connections with mobility support. Currently, there are several trials of the IP multimedia subsystem deployed worldwide that promise to provide telecommunication and advanced(More)
In the last years, a variety of concepts for service integration and corresponding systems have gained momentum. On the one hand, they aim for the interworking and integration of classical telecommunications and data communications services. On the other hand, they are focusing on universal service access from a variety of end user systems. Many of the(More)
Environment-aware Applications and Mobile Communications have proven significant relevance for future telecommunications and computing. This poster describes an approach to integrate heterogeneous off-the-shelf technology to fulfill the demands of environment aware applications. The integration has been done employing a CORBA based middleware. That gave us(More)
In this paper we study the synergy between user behavior, context data, and semantic information in order to enable future services to adapt to different situations based on the recommendations of a service-independent recommender. Therefore, we propose a system that delivers context-aware recommendations, which are based on provided feedback, context data,(More)
