Any common methodology for functionality research in the field of communication systems engineering is network simulation. There is always the overriding worry when utilizing simulation that the results may not reflect appropriate behavior. Therefore, it is important to recognize the particular strengths and also flaws of such simulators. There are a variety of network simulators, as an illustration, NS-2, NS-3, OMNET++, SWAN, OPNET, Jist, and also GloMoSiM and so forth.
As a result, the selection of any network simulator for assessing investigation function is really a critical activity for researchers. The leading emphasis in this research is usually to examine the particular advanced, open source network simulators based on the parameters, CPU usage, memory usage, computational time period, and also scalibility by simulating a wireless sensor network routing protocol, to identify a best network simulator to the investigation area.
