A Semantic P2P Framework for Building Context aware Applications in Multiple Smart Spaces
Source: National University of Singapore
Context information has emerged as an important resource to enable autonomy and flexibility of ubiquitous applications. The widespread use of context information necessitates an efficient lookup service in a wide-area network over multiple smart spaces. In this paper, the authors propose a context lookup framework based on a semantic peer-to-peer network to support the building of context-aware applications in multiple smart spaces. Collaborative context-aware applications that utilize different context information in multiple smart spaces can be easily built by invoking a pull or push service provided by their framework. They describe the design of their system, demonstrate the development process of context-aware applications, and report the measurements obtained from their prototype.
