检测 WiFi 设备的接收信号强度 (RSS)
我目前正在开发一个应用程序，该应用程序应该能够检测该区域的 wifi 设备。我已成功使用 Kismet 检测到这些设备，这让我可以找到该区域中的所有 AP 和客户端（关联或不关联）。然而，除了检测这些设备之外，我还希望知道它们的信号强度，以便尝试在给定时间确定它们的位置。我似乎能够监控这一点的唯一方法是使用 kismet_client （我不想要）并实时显示当前的功率水平。
由于我需要将这些数据提供给将以自动方式运行的事件管理器（Java 中），因此我需要某种方式来捕获它，而不是查看屏幕......（例如，如果某些事件触发了事件）在传感器附近，我想知道它是哪一个设备，假设它是最接近触发它的设备，并且最近的设备具有最高的信号强度）。
有谁知道仅使用 kismet_server 记录/捕获最新 RSS 值的方法吗？
谢谢。
附：如果不使用 Kismet，请推荐一些在 Linux 中使用的其他工具。
I am currently working on an application that should be able to detect wifi devices in the area. I have been successful in detecting these devices using Kismet, which lets me find all APs and clients (associated or not) in the region. However, besides detecting these devices, I also wish to know their signal strength to try and pinpoint their position at a given time. The only way I seem to be able to monitor this is using the kismet_client (which I do not want) and in real time it shows me the current power levels.
Since I need to feed this data to an event manager (in Java) which will be running in an automated fashion I would need some way to capture it, other than looking at the screen... (for example, if something triggers an event near a sensor, I would like to know which device it was, assuming it was the closest one to trigger it, and the closest one having the highest signal strength).
Does anyone know of a way to log/capture the latest RSS value seen using kismet_server only?
Thank you.
ps. if not using Kismet, please suggest some other tool to use in Linux.

我目前正在通过定期检查 kismet netxml 日志文件来执行此操作。该日志文件在“snr-info”标签下显示信号信息。为了检索这些值，我使用 java SAX 解析器。不知道这是否是最有效的方法，但到目前为止似乎有效。
I am currently doing this by checking the kismet netxml log file periodically. This log file presents signal information under the "snr-info" tag. To retrieve these values I am using the java SAX parser. Don't know if this is the most efficient way, but seems to be working so far.
