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

Type of network simulators

Network simulators have two types are

• Open source
  • List of the following Open source network simulators are
    • NS2
    • NS3
    • OMNeT++
    • SSFNet
    • J-Sim
• This tool is very flexible and can reflect the most recent developments of new technologies faster than commercial networks simulators.
• Network simulators that are open source have the advantage of being very open-source, so anyone can contribute and report any bugs. Additionally, the interface can be improved in the future.
• Commercial
  • List of the following commercial network simulators are
    • OPNET
    • QualNet
  • Licenses to use software have to be purchased or users can order specific packages for their usage requirements. 
  • The source code for some network simulators is commercial, so they do not make it available to the general public for free.

We need to note here that, our technical team has got tremendous expertise and advanced field knowledge in all types of commercial and open-source network simulation tools stated here. Therefore you can reach out to us for any kind of support in NS simulation. Let us now have a look into the list of important NS simulators below
