摘要: Sensor networks generate a compact form of data in order to efficiently use the available power device. Query engines require richer this that users can express meaningful and useful queries. This enrichment sensor stream leads an inevitable increase volume transported across network. If is enriched stored database on same server used only for offline queries, matters such as time increased volumes usually be managed quite efficiently. However, when there requirement query output real time, required enrich lead slow response times. In research, we present liveSensor system which offers benefits stream, providing high level interface user. it delays until after results have been generated thus, maintains performance by processing raw streams.
