I have gone though few papers related to this problem. Researchers used NS2.35/2.38. and MATLAB. Also. My particular question is regarding congestion control . Which will be more suitable to use ?
Deepika Gahlan is a packet level network simulator like NS-3. Our team found NS-3 too difficult to use and hence we switched to NetSim which has a GUI for network design, metrics dashboard, plots, analytics, development environment etc.
