[ns] initialEnergy value

[fhg07@c3sl.ufpr.br]

Well, I am running a simulation in which I wanted to obtain a real
environment, thus I tried to calculate how many joules I have in a
Duracell AA MN1500 battery. In the end I got 30779.754 (doubled the result
as I use two batteries). So:
 40 $ns node-config \
 41       -energyModel   EnergyModel \
 42       -initialEnergy 30779.754

Ok, but first of all: I ain't sure about the reliability of this result,
and second of all: After sending 2200 messages, each of them with a Pt_
that covers like 260m, my energy remaining is 30778.725489. After that I
still would be able to send more ~30778*2200 msgs, what seems incredibly
wrong.
(To be more precise, these are the values of Pt_ and Pt_consume_:
Pt_ = 3.16227e-3
Pt_consume_ = 76.2e-3)

That way, I do not know whether my initialEnergy has a too high value due
to incorrect math, or if there is something wrong with the energy
consumption.

Anyone know a reasonable value for initialEnergy, considering that I want
to simulate two AA alkaline batteries? Or if there could be anything wrong
in my energy consumption?



Thanks in advance,
