无线传感器网络节点定位技术探讨

Research on Localization Technology for Wireless Sensor Networks

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。本文在分析了WSN定位算法研究的基础上,对一些改进的定位算法进行了详细的分析,改进的算法能有效地提高定位精度。

It is necessary for the nodes in a wireless gensor 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 location algorithms is discussed on the basis of self-localization algorithms research of WSN, the analysis and comparison of existing algorithms are also studied. Simulation indicates it perfnrms well.
