Hello
i started using Greedy Forwarding using ns 2.33. i have one problem while executing greedy forwarding routing protocol need help solve this error.

num_nodes is set 105

Thank for advance

HOWTO greedy :
Simulation : $ ns-greedy file.tcl

Thank you mr.knud
it work.
After that i simulate and get this error.

ta@VANET:~/Music/ns-allinone-2.35/ns-2.35/greedy/greedy$ ns-greedy greedy2.tcl
num_nodes is set 105
INITIALIZE THE LIST xListHead
Starting Simulation...
SORTING LISTS ...DONE!
Invalid flow flow (53, 3).
ta@VANET:~/Music/ns-allinone-2.35/ns-2.35/greedy/greedy$

simulation is successful, right?, but output file is empty.
can you help me, mr?
thank for advance.

Re #5.
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 ?

thank you mr knud.
i use greedy, cause i want to simulate GyTAR. I have been looking for GyTAR patch, but i didn't get it.
do you have patch for GyTAR?.

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
