Hi,
perhaps you need to check your keyboard and your posting system (whatever it is normal mail or the web interface).
It is well known that posting the same question twice is a nope thing, and only a total idiot would do that.
Since I assume that you're not a total idiot, then there's must be an issue with some software part.
Maybe you posted, the browser got stuck and you posted again thinking that the first message wasn't posted. Yes. probably it's this.
A the moment there's no bluetooth model in ns-3. Perhaps it's because Bluetooth is a hell of a protocol to simulate (it's way more complex than one may think).
About ZigBee, I'm sorry to have to point out this again. ZigBee is not a protocol, it is an industrial alliance.
The ZIgBee alliance defined some APIs and some internal protocols (subject to a quite complex licensing).
Simply talking about ZigBee is like going to someone asking "what car do you have" and the answer is "a Skoda". Dammit, I didn't ask the brand, I asked which car, I want to know the friggin' model !
ZigBee is based on 802.15.4 at phi/MAC level, and that is implemented in the lr-wpan model (but you already know this, because you did read the thread pointed out in a previous message by Kostantinos. Moreover, it's widely dominated in the ns-3 documentation, so only a total idiot would have missed this, and you're not a total idiot (see above).
About the upper layer (up to IP), 6LoWPAN is implemented, RFC 6775 isn't yet implemented, and the other "support" things are being worked on but they have not been released yet.
Summarizing... what car do I have ? A Dacia, why ?
Cheers,
T.
