a context based storage for ubiquitous computing applications
Context-aware systems are computing systems that provide relevant services and information to users based on their situational conditions [1]. Here, first we present a context based storage system that uses context to aid in the capture and access of documents in ubiquitous environment. Then we describe a set of context-aware applications that we have developed within our ubiquitous computing infrastructure utilizing the features of context based storage. Novel features of our system include the access rights mechanism for data and support for group activity. The design and implementation of the storage system presented in this paper contributes to the research of ubiquitous computing by integrating contextual information into the data storage and distributing this information so that it can be accessed on a mobile device, wherever and whenever needed.
