Re: [ns] poission traffic generation for wireless network

Hi J Park,

I don't know about the first tcl warning, but the error that stops your 
simulation -(null)-invalid packet type(exp). -
can be solved easily just adding the proper packet type in cmu-trace.cc
The origin of your error is the default case when the packet type is not 
recognized.

Hope it helps,


Xavier
