Hi,
yes, I see that you are posting in a short time the same question. Please consider that it's August, people could be on holidays, we're not paid to give help and, most important...
1) TDMA isn't a ns-3 supported module. We can not help on unsupported stuff, and this is even more true when...
2) You're using a very old ns-3 release (3.19), when we're at 3.23. Replicating an error on an old ns-3 release is next to impossible.
Unfortunately, I do not have any spare time to debug and fix an unsupported. module. Moreover, the problem of zero-received packets have been already ponited out in the previous thread.
My suggestion is: do your best to understand what the problem is and to fix the module. if you'll succeed, share the results on the original thread along with the full code.
T.
