Abstract Context-Aware Wireless Ubiquitous Computing

Marc Weiser's vision [1] on ubiquitous computing includes the demand for wireless solutions towards a large scale inter-connected environment where all participating nodes are acting autonomously, but transparent to the user. Context-aware computing is one technology to support wireless ubiquitous computing as it enables services and applications in the wireless communication environment to benefit from environmental information. In particular, context aware computing describes a paradigm, where an application uses knowledge related to a set of environmental states and settings to determine and adapt the applications behavior. The work presented in this paper describes an architecture supporting context aware computing in wireless ubiquitous computing environments based on the concept of context spaces as virtual meeting points for communities of ubiquitous computing peers
