摘要 多跳传输原始测量数据的能耗较大,将数据进行分布式网内压缩后再传输的节能方案逐渐为人们所关注。在此从数据融合的角度,对无线传感器网络中各种数据传输技术进行了较全面的考察,着重介绍网内分布式小波变换算法(DWT_IRR)。最后,列表分析比较了几种常见的数据融合技术,并对该领域的进一步发展提出了一些思路。 It wastes a lot of energy to dump all measurements to Sink with multi-hop method,and now a promising way is to do distributed in-network data aggregation before transmission.In this paper,a thorough survey of data transmission technology in WSN is provided in the perspective of data aggregation,particularly the algorithm of DWT_IRR.Typical algorithms are compared in a table,and some directions of future work are proposed.
