[ns] NS for Milti-interface of different radio technology.

[Das Santos Kumar]

Dear NS users,

patch file/ns-extension
Please advise me for the following simulation.

1. I need to simulate a multi-interface based mobile network. The interface are 
of different types such as WiFi, WiMAX, Bluetooth, UMTS and WLAN.

2. Is there any patch file/ns-extension for the above scenario?

3. Instead is there any generic type of patch file/ns-extension for 
multi-interface based mobile node simulation.

Looking forward to see your kind response.

Thanks in advance.

Best Regards,
Santos
