Abstract: Wireless Sensor Networks(WSNs) is applied to environment monitoring and controlling. Since large amount of data is produced when network running, data management is essential to improve the performance of WSNs. This article discusses developments of data management in WSNs, analyzes differences between data management in WSNs and traditional distributed database management system, elucidates the key technologies and main challenges in this area, introduces recent developments in this area, and points out deficiencies about these technologies. Challenge and future research directions of data management techniques in WSNs are outlined.
