trace sources for WIFI to get SINR values

[Shashanka Rao]

I need to know how to connect trace file sources in wifi network to get the sinr values.
PS: I have 1 AP node and 5 users.

The trace source to provide such information is the MonitorSnifferRx from the WiFi PHY class

Using the trace sources is explained in the tutorial/manual

I am trying this from the past 2 days. Can you be me a little more elaborate? can you send an example code for this?

Have you looked at the /examples/wireless/wifi-ap.cc?

That example showcases the use of difference trace sources of WiFi.

Can you give me an example how to use MonitorSnifferRx? I have checked wifi-ap.cc which uses PhyRx trace to get the snr value.
