Abstract: In applications of wireless sensor networks for environment monitoring, the monitoring data collected by the sensor is a typical distributed data streams, therefore, there is a great limitation in the processing of monitoring data using traditional static data processing technology. In this paper, wireless sensor networks for environment monitoring,data stream processing mechanism, and changes in magnitude determine the transmission of data according to monitoring data, improve the bandwidth utilization of the environment monitoring system for environment monitoring of streams data characteristics. Pretreatment module on sensor nodes can simplly process data streams, and the base station can make correlation analysis of distributed data streams.
