摘要
根据无线传感器网络定位技术的研究,不同的网络环境必须采用适合的定位技术才能达到较好的定位效果。本文通过设置两种不同的煤矿环境(即煤矿通道环境和煤矿井下环境),从不同方面对四种基于非测距算法的定位性能进行仿真分析,得出了重要结论:质心算法最适合应用于狭长的通道仿真环境,而DV-Hop最适于未知节点密度高,信标节点少的井下密集型环境。
According to the research of wireless sensor network location technology,different network environment must use suitable location technology to achieve better location effect.This article through the setting two different coal mine environment（i.e.channel environment and underground environment of coal mine）,from different aspects carry out simulation analysis to four location performance based on range-free algorithm,obtain the important conclusion： centroid algorithm is the most suitable for long and narrow channel simulation environment,and DV-Hop is the most suitable for the underground intensive environment of the unknown nodes high density and less beacon nodes.
