Hello All,

I was modifying energy-model.h and getting really strange results - I was
trying to add other features and I was finding out that it would stop
working - though the code I was adding was not at all complex - nor was it
interfereing with other code.

In order to narrow down what the problem was I kept eliminiating lines of
code until I had only two left -  adding two integers to the set of
protected variables in energy-model.h

The two lines were:

	int number_of_tx_;
	int number_of_rc_;

(around line 160 in the ns2-1.b7 version of energy-model.h)

The scenario I was running would put out quite big nam/tr files (over
20 Megs each) - but with the two lines aboe around 20 K each.

I am including the tcl files along with the modified energy-model.h file.
I would appreciate an explanation as to why adding the above two lines
seems to hose up the system.

Thanks

raju
