At present, there have been researches on using XML to integrate heterogeneous data sources, but most of the research targets are heterogeneous databases, and XML is used as an intermediate form of data exchange between databases. As for how to aggregate contextual information in pervasive computing, t

A polymerization method of context facing to general fit calculation is to solve the isomerization performance of context information in the general fit calculation, according to the characteristics of the context in the general fit calculation, combining with the expandable making language XML, the inconvenience for finding context calculation brought by the isomerization performance can be effectively shielded, the scheme can increase the time information when performing instantaneous variation type context time polymerization and form polymerization, which is propitious to find the context calculation, the screen selecting and the application of the context can be performed by the calculation time.
Description
technical field [0001] The present invention proposes a context aggregation scheme for pervasive computing, uses XML technology to solve the heterogeneity of context information in pervasive computing, and belongs to the problem of pervasive computing context collection and aggregation. Background technique [0002] With the support of new devices, people can conveniently access and operate the required information anytime and anywhere according to their needs. This is ubiquitous computing. Ubiquitous computing has two important concepts: context and context-aware computing. Context is any information that can represent the state of a physical entity and its environment; context-aware computing means that whenever a user needs it, the computing device can use the context to provide the user with information or services suitable for the local task at that time. The realization of ubiquitous computing requires that the information space can collect the context information of ...
