Hi.
FSR and OLSR are both main protocols. Usually not used together.
... Why not just setup another ns-allinone-2.35 ?
/home/name/ns2/olsr/ns-allinone-2.35/
/home/name/ns2/fsr/ns-allinone-2.35/
etc.
You can have have as many ns-allinone-2.xx as you want, installed at the same time
(My example is attached : All executable 'ns-name' are supposed to be in /usr/local/bin/)
Or do you want to run combined OLSR / FSR simulations, with two complete sections of node-config with different protocols ?
