[ns] total tx power in energy-model.cc - how to display it?

[Chuah Seong Ping]

Hi all,

 

I want to know the total transmission energy of a wireless node. I
initiated the energy model by:

 

$ns_ node-config -energyModel $energymodel \

-rxPower $p_rx \

-txPower $p_tx \

-initialEnergy $initialenergy

 

There is this variable et_ in /mobile/energy-model.cc to keep track of
the transmission energy.

 

But how do I pull out this variable to display its value? I tried to
show it through printf but the NS simulation didn't print its value as
stdio! In fact, all printf messages inserted in /mobile/energy-model.cc
, /mac/wireless-phy.cc , /mac/mac-802_11.cc were not shown as stdio! 

 

Can anyone please advice? 

 

Millions thanks in advance.

 

Regards,
