How to make IEEE 802.15.4(ZigBee) mesh network in ns3

[non]

Hello everyone.

I've a question and want to your knowledges.

Now, I'm building a simulation using ns3.26.

My finally proposal is to simulate ZigBee Mesh Network.

So I try to do Low-Rate Wireless Personal Area Network (LR-WPAN) example and mesh example.

But I can't understand how to docking the two.

Could you give me some advices?

Thank you.
