Abstract: It is a very common practice to use network simulators for testing different network performance parameters before the real-life deployment of such a network. Simulation results across different simulators should be in close agreement with each other and must be dependable. Apart from ns-2, few other recent network simulators have come into existence today and are gaining in more popularity. Thus, it is evident that a qualitative comparison should be made about which simulator should be used. In this study, researchers survey some of the widespread network simulators that are in use today and try to evaluate their performance over certain parameters by setting up identical network simulation scenarios. The results that are obtained from the experiments conducted are analyzed in detail.
