| 摘 要： | 在无线传感器网络中，测量节点间的距离对节点定位非常关键。在部署无线传感器网络时，节点是随机布撒的，在没有定位机制或者手工测量的情况下，节点的位置信息不能预先知道。提出采用基于窄频RF的TOF测距方法来估算两个节点间的距离，该方法性能较好，但它在无线传感器网络定位技术中尚未普遍应用。采用Jennic JN5148平台在不同的室内外环境中进行TOF测距的实验。结果表明，基于RFTOF的测距方法在室外100m处的测距精度为±4m，在室内10m处的测距精度为±2m，可以很好地满足无线传感器网络定位技术的需要。

| Abstract: | The ranging between nobes is critical for the nobe positioning in the wireless sensor network.In the deployment of wireless sensor networks(WSNs),nodes are randomly dispensed,so the location information of the node can not be obtained in advance.The TOF(time of flight) ranging method based on narrowband RF is proposed to estimate the distance between the two nodes.However,it is not widely used in the localization technology of WSNs.TOF ranging experiment was carried out with a Jennic5148 platform in differe... |
