What is meant by the NS simulator? Using a network simulator, a network model is created to study how different network devices (Like access points, routers, wireless devices, radios, Mobile phones, satellites, etc.) interact to provide seamless data transmission.

Through this article, you will get a detailed overview of the NS simulator. Here you can get a complete understanding of all aspects of NS simulation including its uses, types, and workflow, and so on.

Benefits of NS simulator

  • Using mathematical formulas, the behavior of a computer or a communication network can be modeled by simulating the interaction between the components.
  • External devices can be used to test applications via simulators.
  • Simulation tools are used to analyze networks’ network performance, application performance, and device performance.
  • Models of real-world networks are used in network simulators.

These are the major benefits of the NS simulator. Due to all these merits, NS simulation is gaining importance among researchers in many of the advanced areas of research these days. Let us now discuss the kinds of network simulators
