Greedy is equally easy to build, but I never got any of the examples to work :
greedy.tcl, greedy_test**.tcl .

HOWTO greedy :

sudo apt install g++-4.8 

tar xvf ns-allinone-2.35_gcc5.tar.gz
https://drive.google.com/file/d/0B7S...ZNRGVORjQ/view
cd ns-allinone-2.35/
patch -p0 < greedy_ns235.patch
export CC=gcc-4.8 CXX=g++-4.8 && ./install
cd ns-2.35/
cp ns ns-greedy
sudo cp ns-greedy /usr/local/bin/
Simulation : $ ns-greedy file.tcl

Invalid flow : Is a fatal error.

As I wrote in https://groups.google.com/forum/?fro...rs/8aK3SIcGyys
... I never got any Greedy simulation to work.

? Why don't you use the more advanced GPSR-hls or GPSR-KeLiu ?

Re #7.

"greedy traffic aware routing (Gytar)"

No patch. I have searched for ``ns2 Gytar´´ sometimes over the years.
. https://www.linuxquestions.org/questions/tags/gytar/
. https://groups.google.com/forum/?fro...ar%7Csort:date

There is an example for ns3 ( gytar-example.cc )
https://10343742895474358856.googleg...aUJ01I7BjJ72Gc
... So I guess you can use ns3
