摘要

我们展示了一种基于直方图距离的无线电断层成像(HD-RTI)的交互式演示，这是一种无设备定位(DFL)系统，它使用无线网络静态链路上接收信号强度(RSS)的测量来估计部署区域内佩戴任何无线电设备而不参与系统的人员的位置。与之前基于RSS的DFL方法相比，使用直方图差异度量是一种非常准确的方法，可以量化与历史度量相比链接上RSS的变化。新方法非常精确，并且比以前的方法使用更低的节点密度。

Demo abstract: Histogram distance-based radio tomographic localization

We present an interactive demonstration of histogram distance-based radio tomographic imaging (HD-RTI), a device-free localization (DFL) system that uses measurements of received signal strength (RSS) on static links in a wireless network to estimate the locations of people who do not participate in the system by wearing any radio device in the deployment area. Compared to prior methods of RSS-based DFL, using a histogram difference metric is a very accurate method to quantify the change in RSS on the link compared to historical metrics. The new method is remarkably accurate, and works with lower node densities than prior methods.
