A Performance Evaluation of Commonly Used Network Simulators

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. Apart from ns- 2, few other recent network simulators have come into existence today and are gaining in more popularity. In this paper, we 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.
