Regarding simulator for Zigbee network

As I know, there is no simulator for this.

sir,
thanks sir, u said there is no simulator.
But I want to extend my network but money matters for me. Can u suggest any idea for this.
My aim is , there is an attack happens in my network.
There is one more node with same address in different location i want to identify this.
Can u help to sort out this problem. I am so helpless.

Don't know how you help you to simulate 1000 nodes. If there is an attach happens to any network, there is no way to avoid it.

James ,
thank you. I know that ns-2 can be used to simulate but i dont have any idea about ns-2. I don't have time to study ns-2. Can u give me some already available programs which implements a Zigbee network.

Checkout Cooja network simulator.

Also there is Zboss network simulator but their page () has been down for a week now.

Best regards

thank u .
i will check and i will get back soon if there is any problem.
whether u have worked with Zboss if u have any sample code pls send me.
