Currently 2 simulators are being considered: OverSim and ns-2. Although the OverSim is preferred by the professor, I still don’t have too much sense about a network simulator itself X-@. I spend 3 hours on the documents of OMNeT++ and OverSim, as well as compiling them. Thanks to their well organised documents, the OverSim is now setup and able to run on my laptop.
Amos this morning informed me that his code I was using was outdated. He has a newer version which performs much better. He made a lot of improvements on it in order to make it suitable for my experiments. Thanks him!
