摘要
无线传感器网络是一种新兴前沿技术,其巨大的应用前景受到学术界和工业界的高度重视。无线传感器网络节点能量和计算资源严重受限,数据融合技术是减少网络能耗、降低数据冲突、降低传输时延的重要方法。本文首先分析数据融合的重要性;其次针对数据融合的功能分类阐述现有的数据融合方法,并分析存在的问题;最后对数据融合技术的未来发展进行了展望。
Data aggregation is the front line of technique,more and more academic researchers and people from industry are engaged in developing wireless sensor networks due to the great promise and potential with various applications.Aiming to the severe energy and computing resource constraints of wireless sensor networks（WSN）,data aggregation is a very important technique that assists it in decreasing the energy consumption,cutting down time delays and decreasing overhead of the transmission during the process of data collection in a wireless sensor networks.This paper introduces the function and significance of data aggregation,specifies the existing and typical classification of data aggregation,points out the direction and prospects of data aggregation in WSN.
