"Queue/LTEQueue"

while executing

"Queue/LTEQueue set qos_ true"

(file "lte.tcl" line 21)

best regards

Instead of NS-2, you have to use MATLAB . It is user friendly simulation

thank you for all 

can not move to matlab in the time don't have more time also no idea matlap in network  

i need only patch lte in ns-2.31 on cygwin and how configuration it plz

thand you again

If you can work with c++ then better move to NS-3 as you are not familiar with Matlab.

i need only to build scenario lte with enhancement tcp (modified code )

OPNET Modeler is a good choice for LTE
