普适计算中一种上下文集成方法
Context Integration Scheme in Pervasive Computing
摘要
Abstract
As a novel computing mode, pervasive computing provides services anytime, anywhere according to users' demands. In this environment, many heterogeneous data sources affect the efficiency of context processing and accessing. It presents a XML-based context integration method, which can reduce the amount of context storage, shield the heterogeneity, and provide a unified expression of context information on the premise of ensuring the precision and freshness. Furthermore, test results show thai this method can speed up the integration by retaining a copy of document in memory and using file-partition strategy, and enable pervasive computing services more efficiently.关键词
