A List of Network Simulation Tools , provides a comprehensive list of network simulation tools used by us. We can suggest you best simulator as per your project concept and domain.

It will make your project more effective and proficient to fetch high grades. Approach us for any kind of support regarding any network simulation concepts and projects. Network Simulation tools is design to construct a large network, where you can analyze the performance of the network using few performance metrics.

When a user wants to make a new network object, he can either write the new object or assemble a compound object from the existing object library, and plumb the data path through the object. This plumbing makes NS2 very powerful. Another feature of NS2 is the event scheduler. In NS2, the event scheduler keeps track of simulation time and release all the events in the event queue by invoking appropriate network components.

All the network components use the event scheduler by issuing an event for the packet and waiting for the event to be released before doing further action on the packet. Similar to NS2, NS3 is also an open sourced discrete-event network simulator which targets primarily for research and educational use. NS3 is designed to replace the current popular NS2. The major difference lying between NS3 and NS2 includes:. Figure 3 gives an example virtualization testbed of NS3. However, NS3 is still in the process and some major challenges still remain for NS3 to solve.

The biggest one is that NS3 needs participation from the research community. Firstly, the simulation credibility needs to be improved.

We know that one of the limitations of simulations, in general, is that it often suffers from lack of credibility. Generally there are four points that are important for NS3 to solve this problem. They are:. Secondly, NS3 is intended to replicate the successful mode of NS 2 in which a lot of different organizations contributed to the models and components based on the framework of NS2.

The following figure illustrates this status:. Specialized maintainers can play a key part in the system. In NS3, the active maintainers are required to respond to the user questions and bug reports, and help to test and validating the system. All in all, NS-3 is an active open-source project and it is still under development.

It has several simulator features designed to aid current Internet research. It is also a community-based development and maintenance model, which needs more people and organizations to participate to contribute before it become good enough for the Internet research community.

Its primary application area is communication networks. It is a component-based architecture. The components are then assembled into larger components and models by using a high-level language. The library also includes the infrastructure to assemble simulations from different components. Besides these, there are also runtime user interfaces or environments for simulations, and tools to facilitate and manage simulations. It provides an infrastructure for writing different simulations.

Specific application areas' requirements are met by different simulation models and frameworks, most of which are open sourced. There is also a mailing list for the general discussion. Actually it is currently popular as a network simulation platform in the academia as well as in industry, and build up a large user community. This paper is to offer a general overview on the current development status of network simulators for the people who are not very familiar with this topic, or for someone who want to get some general information related to it.

So in this paper, we first gave a brief introduction on some key concepts of network simulation and network simulators. Their main features, current status and future development are also analyzed and discussed. As an assumptive expectation, the open sourced and well designed embedded Object-oriented programming feature will be appealing to the academia and industry in the long run.

It seems that the easier for the users to learn and to use, the more organizations participate in, the more specialized in the documentation, the more development and popularity that simulator will achieve.
