network simulation using ns2 software

Question

When executing the following code: I faced this error:

ns2 AOMDV simulation error

Network is not my field. thus I need your help seriously.

num_nodes is set 0

Graphical, ns2 APP-Tool https://github.com/WiNG-NITK/APP-Tool
Ubuntu 16.04 can use APP-Tool, i.e. it's a Python2 application The awk files APP-Tool/Final/[file].awk are using the new trace format

set ns [new Simulator]
$ns use-newtrace
$ns set WirelessNewTrace_ ON

The "newtrace modified" 111_aomdv-2.tcl is named newtrace-111_aomdv-2.tcl, creating a trace file 1new-mdaomdv.tr. https://drive.google.com/drive/folders/14vdJfoIqqKj34clkdxuN0IclHc0o0Oml?usp=share_link
Using newtrace : Many more of the available awk scripts can be used with the "1new-mdaomdv.tr"
