The institution is not in a position to purchase the software now so am left on alone to look for it. Anyone who can help me with it? I will really appreciate. I have tried with omnet++ and wanted to see the response of a tetcos netsim simulator!
Hello Rop, I dont think there is any free version available. Also, you need the licensed version to get tech support (which you might need if you are doing R & D by linking SUMO to NetSim for VANET etc). I understand educational institutions can get it at discounted academic prices.
