摘要
无线传感器网络定位在当前需求的推动下,已经成为热点研究领域。本文分别从定位方式、定位技术以及定位原理3个方面对无线传感器网络定位研究进行了梳理并展开了综述;其次,分别对3种基于无线传感器网络的定位算法进行了描述;然后,阐述了目前无线传感器网络定位的热点问题,其中,针对定位研究中非视距干扰问题,分别从非视距误差的数值特征和统计特征两个方面的研究现状进行了分析,并对基于多传感器融合的无线传感器网络定位方法进行了分析和总结;最后,针对无线传感器网络定位应用的挑战进行了展望。
Driven by current demand,wireless sensor network localization has become a hot research field.First,in this paper,the research on wireless sensor network localization is summarized from three aspects:localization method,localization technology,and localization principle.Second,three localization algorithms based on wireless sensor networks are described.Third,the hot issues on wireless sensor network positioning are described.Aiming at the non-line-of-sight(NLOS)interference problem in localization research,the research status of the NLOS error is analyzed from two aspects:numerical and statistical characteristics.In addition,the localization methods of wireless sensor networks based on multi-sensor fusion are analyzed and summarized.Finally,the challenges of applying wireless sensor network localization are discussed.
