[ndnSIM] How to add LTE module into ndnsim-car2car？

[Alex Afanasyev]

Hi Quan,

You may want to edit wscript file (line 64) and add lte to the list of NS-3 modules that the scenario requires.  This way, the scenario will be linked to LTE module as well and you should not get the compilation error.
