A question asked by many: which network simulator should I use for my thesis or research? The answer is with you. You have to explore and find your needs of research work or thesis; dig into the matter; then plan accordingly. If you have not read previously, I suggest you to read an article How to choose the best Network simulator for your research/thesis work?

Some Network Simulators Softwares

Middleware extensibility and integration modeling of your research findings can be understood only by yourself perspicuously. Hence, you need to compare which network simulator does the best job for you. Network modeling and simulation is possible in all of the following simulators.

So, Which Network Simulator should are you? I have prepared a comparative table of frequently used and popular network simulators which I happen to encounter during my research in Heterogeneous Wireless Sensor Networks (HWSN). Maybe emphasis has been given on Discrete Event-based Simulators. Listed here different simulators available for Simulation regarding network topology and connections.

Comparing network simuators:

We include MATLAB, NS 2 and NS 3, OMNeT++, Castalia,  TOSSIM, Ptolemy II, Tiny OS, J-Sim, NetTopo, Sidh, GloMoSim, QualNet, etc etc. This is just a short list, I know there might be a large list of Network simulators and emulators, frankly I have not covered commercial ones except few.
