在设计无线传感器网络时,基本的问题是克服能量与带宽的限制。数据融合作为一个基本的方法,其目的是减少传感节点间的传输量,达到降低整个网络中的能量消耗和数据冲突。为了对当前在无线传感器网络的数据融合问题的研究工作做一个全面的总结,根据自组织性和网内处理2大类对现有研究成果进行分类,并从传输方式、网络拓扑、时钟同步、融合函数、多信号处理等多方面对当前的研究成果进行细致划分和精炼比较,为当前在这个领域的工作做了较好的综述。
The basic problem in designing wireless sensor networks is overcoming the energy and bandwidth constraints. Data fusion as a basic method, the purpose is to reduce the transmission between sensing nodes, to reduce the energy consumption throughout the network and data conflicts. In order to make a comprehensive summary of the current research work on data fusion in wireless sensor networks, the existing research results are classified according to the two major categories of self-organization and intranet processing, and from the aspects of transmission mode, network topology, clock synchronization, Fusion function, multi-signal processing and other aspects of the current research results detailed and refined comparison, for the current work in this area made a good overview.
