Preprocessing for Aggregation over Data Streams in WSN
Baolin Yi · Journal of Guangxi Normal University · 2007
A preprocessing algorithm for aggregation over data streams in wireless sensor networks is proposed.The sensor node gathers data from target area and constructs a query set over data stream.To obtain the results corresponding to the given query,the sensor node first selects the most available information in query temporal interval and then forwards the aggregation information to other nodes in the routine till sink node.The strategies can improve the efficiency of sensor node and data precision.
