What are the important Network Traffic Simulators?

         Several Network traffic simulators are widely employed for network-based research. Below, we suggest various traffic simulation tools like NS3, NS2, MATLAB, and OMNeT++ together with their applications, characteristics, and their variations among one another:

NS3 (Network Simulator 3)

• Features: Significantly, NS3 is modeled for academic and research objectives in computer networking. The simulation of IP as well as non-IP related networks are assisted by this simulator. For extensive network protocols, kinds of traffic, and devices, it provides frameworks. It is also referred to as a discrete-event network simulator.
• Applications: In analyzing network’s efficiency and activities based on different circumstances, NS3 is widely helpful. For simulating networking situations like multitask, TCP/UDP performance, wireless networks (such as WiMAX, LTE, Wi-Fi), and routing, it is employed in an effective way.
• How It Differs: For simulation arrangement, NS3 does not depend on Object Tool Command Language (OTcl) contrary to its previous simulator NS2. Utilizing C++ and Python, NS3 is built. In simulations, it provides high efficiency and adaptability.

OMNeT++

• Features: OMNeT++ is crucially utilized for constructing network simulators. It is examined as a modular, flexible, component-related C++ simulation library and model. Particularly, it offers the aspects for developing simulations in different fields, but it is not considered as a network simulator itself.
• Applications: Adaptability of OMNeT++ enables for application over networking such as the multiprocessor and distributed framework simulations, queuing networks, and other specific frameworks, even though it is extensively employed for academic and network research.
• How It Differs: OMNET++ supports the creation and debugging of frameworks, because it is highly recognized for its robust GUI-related runtime context. It is also appropriate for developing complicated, broader simulations due to its nature of flexibility and reutilization of frameworks.

MATLAB (Matrix Laboratory)

• Features: For various processes like numerical computation, visualization, and programming, MATLAB is highly employed and it is considered as a high-level programming language and communicative platform. It can be utilized for traffic simulations with its wide range of toolboxes and Simulink, although it is not a network simulator. For multidomain simulation and model-related design, it is examined as an extension.
• Applications: In wireless interactions, MATLAB is implemented for simulating signal processing, interaction protocols, and network design. For designing and examining transportation systems, control systems, and vehicle dynamics in traffic simulations, MATLAB and Simulink are widely employed.
• How It Differs: MATLAB is highly appropriate for extensive applications over network or traffic simulation, because of the effectiveness in its larger library of pre-designed functions, easy visualization of complicated data, and numerical computing abilities.

NS2 (Network Simulator 2)

• Features: NS2 is specifically modeled for networking research and it is referred to as an openly-accessible simulation tool. For the simulation of routing, TCP, and multicast protocols beyond wireless (like satellite and local) and wired networks, NS2 offers significant assistance.
• Applications: It is more helpful for academic objectives to interpret network standards and also supportive to examine protocol analysis and network activities. NS2 is flexible for network research, because it assists a huge amount of Internet protocols.
• How It Differs: Through the utilization of OTcl, NS2 simulations are designed and are widely recognized for including a steep learning curve. Because of the wide range of previous studies and accessible reports, NS2 is considered as prevalent rather than its low performance-based and older than NS3.

In various kinds of simulation missions, each of the above specified tools is particularly appropriate because of their specific effectiveness and characteristics:

• For network simulations, NS2 and NS3 are considered as highly specific and skillful. In that, NS3 provides greater efficiency and latest characteristics.
• OMNeT++ is not constrained to network-based research. For developing different simulation scenarios, it offers an adaptable model.
• In numerical computations and system-related simulations, MATLAB with Simulink is more skillful. For extensive engineering missions over networking, it is very appropriate.
