[ns] Help: Received Power Level of a Packet at MAC Layer in MANETs

Tue Apr 16 05:15:49 2002

The receive power of a packet p is stored in the variable
    p->txinfo_.RxPr
You could either print this variable anywhere in the code using the printf
statement. If you want a cleaner solution, you will have to figure out
exactly where the packet is being traced (i guess it should be in
cmu-trace.cc) and then include this variable in the trace info
hope this info is useful.

Hi All,

I am new to NS2 and am currently running simulations
of wireless mobile ad hoc networks (MANETs) based on
the 802.11 MAC protocol.

I would like to get a trace of the received power
level of every packet at the MAC layer (802.11) of
each node.

I tried turning the MAC layer tracing on but that
doesn't trace the received power level.

Can someone suggest some way for me to get this trace?
I looked at the code and I can see that the 802.11
layer is aware of the received power level of a packet
but I can't think of a way to trace the value.

Any help or suggestions would be appreciated.

Thanks,
Ankit.
