Towards using data aggregation techniques in ubiquitous computing environments

Ubiquitous computing envisions the era of computing where pro-active computing services are available to all any where, any time. In order to provide such pervasive services, an ubiquitous system collects a large amount of information continuously from its physical and computational environment. Managing and manipulating this information optimally is one of the most important aspects of ubiquitous computing system. We have proposed formal schemes for the storage and management of this information using the summarization techniques. We prepare aggregates or summary of information present in the repository and try only to use these summaries and aggregates most of the time for query processing. This approach not only saves the storage space but also results in efficient distributed and mobile data processing
