摘要
WSN(无线传感器网络)的许多应用都是基于节点的位置信息,传感器网络由于节点数量巨大,资源十分有限,全部节点都采用GPS定位设备是不适宜的。该文在分析了WSN定位算法研究的基础上,分析了近年来提出的基于距离无关的定位算法,这些算法能有效地提高定位精度。
It is necessary for the nodes in a wireless sensor networks to know their location.Because of constraints in size,form factor and cost of construction of sensor nodes,it is imp-ractical to use GPS receiver at each sensor node.In this paper,the classification of range-free location algorithms is discussed on the basis of self-localization algorithms research of WSN,the analysis and comparison of existing al-gorithms are also studied.Simulation indicates it performs well.
