We provide a summary based on how you could utilize the abilities of NS-3 by means of its modules, settings, and metrics:
NS-3 Modules

Parameters
To modify the simulation, every module accompanies a collection of metrics which could be adjusted. Scholars are enabled to investigate in what manner the effectiveness of the network is impacted by various arrangements by altering these metrics. Some of the instances of metrics are:
- Transmission Power: We are able to determine the transmission power of Wi-Fi devices in the Wi-Fi module.

- Channel Models: In wireless simulations, it is significant to indicate the fading framework or the propagation loss framework.
- Traffic Generation: For creating network traffic, like start/stop times, packet size, and interval, configure metrics through the utilization of the Application module.
Settings
Appropriate to design and simulate certain network simulations or experimentations, NS-3 settings are certain configurations. Generally, the following steps are encompassed while constructing a setting in NS-3:
- Topology Design: The kind and number of nodes such as switches, routers, clients, servers, and in what manner they are linked has to be determined.
- Protocol Configuration: The protocols that we plan to employ at various layers such as UDP or TCP at the transport layer ought to be selected. Focus on configuring their metrics in a proper manner.
- Simulation Execution: By means of the capability to record or visualize the process and results, it is significant to execute the simulation for a given period of time.
- Result Analysis: In order to create conclusions, our team plans to gather and examine data from the simulation.
Instance Setting: Simulating a Wi-Fi Network
To simulate a simple Wi-Fi network with the support of NS-3, we offer a detailed summary of procedures:
- Set the Wi-Fi Module: Initially, Wi-Fi devices should be configured. It is advisable to indicate the Wi-Fi principle such as 802.11n.
- Arrange the Mobility Model: To Wi-Fi nodes, a mobility model must be allocated. For mobile nodes, the RandomWalk2dMobilityModel could be utilized.

Kindly please I need your help related to the NS3 simulation I see many papers that set the simulation time to the 1800s so is it random or based on something
As indicated in numerous research papers, the process of selecting a simulation time of 1800 seconds or 30 minutes in NS-3 simulations is on the basis of particular aspects related to the major goals of the simulation study but it is not arbitrary. We recommend some justifications for what this time could be selected:
- Representative Duration for Network Behavior
In order to inspect and explore standard utilization trends, an adequate time limit could be offered by a 30-minute window for numerous network settings. Specifically, user activities such as voice over IP, web browsing, or video streaming could be encompassed. Among sustaining simulation times to be attainable as well as seizing eloquent data, it moderates.
- Benchmarking and Consistency
Generally, various network protocols or arrangements are assessed in opposition to each other in comparative studies. For comparison, it is significant to have a logical foundation. Among various settings or studies, a reasonable comparison of outcomes is enabled through the utilization of a typical simulation time such as 1800 seconds. In specific regions of network study, this time has turned out to be partially a practice. For assessing and explaining outcomes, a guideline could be offered.
- Computational Feasibility
The time needed to accomplish a simulation as well as computational resources are influenced by simulation time in a straight manner. In opposition to computational and time overheads connected with executing simulations, related data should be collected. For that the need to simulate sufficient periods of time could be stabilized by thirty minutes which is examined as a realistic decision. Excessive amounts of computation time and resources could be needed by extensive simulations for complicated network systems, mainly those with large quantities of nodes or complicated communications.
- Steady-State Conditions
It is necessary to examine the framework once it has attained a balanced condition, in few network simulations, specifically those encompassing dynamic routing and traffic flows. Since traffic trends balance and routes are determined, transient activities could be encompassed by the preliminary stage of a simulation. To enable these transient situations to diminish, a 30-minute duration is a sufficient period of time. Under the steady-state process, the exploration of the network could be facilitated.
- Real-world Relevance
For seizing user communications, high traffic volumes, and other events, a practicable time limit could be offered by 30 minutes for simulations intended at imitating actual world settings like the effectiveness of a network under standard operating environment. This timeframe makes the simulation outcomes more appropriate as well as significant by most closely resembling the operational access of specific network behaviors or the timeline of standard user sessions.
Customizing Simulation Duration
On the basis of the certain objectives of your research, the range of particulars needed, and the network settings being simulated, the perfect simulation duration is determined even though 1800 seconds is considered as a prevalent choice. It is significant to reflect on:
- Research Objectives: The simulation time must be coordinated with the goals of your research. As a means to seize the important aspects, focus on assuring that it is a sufficient period of time.
- Computational Resources: In addition to sustaining research requirements, the simulation timeframe ought to be adapted to align within accessible resources. For that the computational practicability has to be evaluated.
- Precedents in Literature: As a means to interpret usual approaches, it is advisable to analyze relevant work. On the basis of recognized standards or new necessities, your selected simulation time ought to be explained.
