[ns] Buffer Size Parameter

[kalpa sankara]

Hi All

I am using the NIST patch for WiMAX module with NS2.

Does anybody know how the buffer size parameter is set at the Base Station. 
Packets get dropped due to delay.
This is due to buffer size capacity at the BS. I want to know what is the 
default buffer size and how to modify it.

Kindly help me .

Thanks
