OMNEST - OMNeT++ Comparison

OMNEST is the commercial version of OMNeT++, one of the most popular network simulation frameworks in academic and research communities. OMNeT++ is distributed under the Academic Public License, which does not allow commercial use.

OMNEST and OMNeT++ are nearly identical. Simulation models written for OMNeT++ are guaranteed to compile and run with OMNEST, and vice versa. Differences apply to licensing, packaging, and certain features only.
