ns2 nam console empty with no nodes
Hello ns2 experts,
What may be possibly wrong with this program?? I am getting empty nam console without any nodes seen. Also while running the program, I am getting "node is not defined" for a million times on my unix console.
Trace and NAM trace files seems to be fine
Please look.
I am using NS2.35 on ubuntu 14.04, 64 bit OS
THank You
