An Effective Approach for Continuous Window Query in Wireless Sensor Networks1

摘要

In this paper, we propose FCWQE, which is effective supporting continuous window query in wireless sensor networks. And it includes FCDC (Four-color with Delay Computation) approach to color the sensors, partition the logic aggregation groups and build the query-path. In order to save the energy and prolong the networks lifetime, this paper brings forward strategy to choose group leader nodes; at the processing of data collection, DAQ (Data Aggregation based-on Query-path) is proposed to deal with the data transmission among groups.
