make wifi node promiscuous mode

[Bin Ni]

Hi all,

I have one question to bother you that I would like to make the Wifi
node working as promiscuous mode so that I could enable the node
capture each packet it hears on the air. I think currently the default
mode is non-promiscuous mode. How could I change it to promiscuous
mode?

I know in Node.cc I found this

device->SetReceiveCallback (MakeCallback
(&Node::NonPromiscReceiveFromDevice, this));

I simply changed the line to

device->SetReceiveCallback (MakeCallback
(&Node::PromiscReceiveFromDevice, this));

because Node::PromiscReceiveFromDevice is already there....

but it couldn't be compiled.

Anybody did the same case before? I will appreciate you so much if you
could offer me any hint about that...

Thanks!

Regards,
Bin

I do not think you really need to force promiscuous mode on everything.  NS-3 has "promiscuous procotol handlers", instead of "promiscuous mode".

See Node::RegisterProtocolHandler, there is an optional parameter 'promiscuous', whose default value is 'false', you can also register a handler with promiscuous value 'true'.

I suggest you to have a look at the following example, which uses
promiscuos mode with wifi:
