In the wireless sensor network monitoring system,redundant data caused by slow environmental changing and overlapping sensing range of nodes will increase the amount of data sent by sensor nodes,reduce the efficiency of information collection,and lead to premature death of sensor nodes.Therefore,this paper proposes an intracluster data fusion scheme based on ring buffer.All sensor nodes use ring buffers to store data.Based on the ring buffer,the source node adopts the bina-rized similarity function and sliding quartile detection method to eliminate redundant data and transient abnormal data wh...
