How to simulate wifi network?

NS-3 is a most famous network simulator for both academics and research. It is a discrete-event network simulator for internet frameworks. We suggest you a simple approach on simulating a WiFi network properly through NS-3 simulator:

Step 1: Choose a Network Simulator

• Along with the complete frameworks for IEEE 11 a/b/g/n/ac/ax qualities, NS-3 is broadly implemented for its huge assistance for WiFi simulations.
• There are some other choices like OPNET Modeler, OMNeT++ and MATLAB’s Simulink with Communication Toolbox.

Step 2: Install the Simulator

• Especially for NS-3:
• From the official website, download the latest version of NS-3.
• For your specific operating system like Windows, macOS and Linux, it is necessary to adhere to the installation guidelines.

Step 3: Understand the WiFi Model in the Simulator

• For simulating WiFi networks, NS-3 offers frameworks the contains the properties such as:
• Various IEEE 802.11 standards.
• AP modes, architecture and Ad hoc.
• Layer configurations of MAC and PHY.

Step 4: Create a Simulation Script

• To state the parameters, network topology, and devices, you should write a simulation script in C++ or Python when assisted by the simulator. Your script will commonly include the following aspects for a basic WiFi network simulation in NS-3:
• Node Creation: Explain WiFi access points (APs) and user devices which are denoted by the nodes.
• WiFi Device Configuration: By indicating the channel width, all PHY/MAC layer parameters and WiFi standard like 802.11n, create WiFi devices on nodes.
• Mobility Model: When required, the mobility designs such as random walk or static for nodes have to be described.
• Application Layer Setup: To produce traffic like sinks and TCP or UDP traffic sources, configure network applications.
• Start the Simulation: Begin the simulation by mentioning the timeframe of the simulation.

Step 5: Execute the Simulation and Collect Data

• Run the script of the simulation.
• Signal strength, packet loss, delay and throughput are the performance metrics that have to be gathered. To collect this data, NS-3 provides different logging and monitoring choices.

Step 6: Analyze Results and Iterate

• Interpret the efficacy of the network on the simulated criteria by observing the gathered data.
• To discover various features of Wi-Fi network activity, alter parameters and situations in terms of your detections.

Example: Basic NS-3 Simulation Script

To simulate a simple WiFi network, we give this basic example of an NS-3 script snippet:

// Basic includes for WiFi simulation

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/mobility-module.h”

#include “ns3/wifi-module.h”

#include “ns3/internet-module.h”

using namespace ns3;

int main (int argc, char *argv[])

{

// Disable fragmentation and RTS/CTS

Config::SetDefault (“ns3::WifiRemoteStationManager::FragmentationThreshold”, StringValue (“999999”));

Config::SetDefault (“ns3::WifiRemoteStationManager::RtsCtsThreshold”, StringValue (“999999”));

// Create nodes: 1 AP and 1 station (STA)

NodeContainer wifiNodes;

wifiNodes.Create (2);

// Set up WiFi devices and channel

WifiHelper wifi;

wifi.SetStandard (WIFI_PHY_STANDARD_80211n_5GHZ);

YansWifiChannelHelper channel = YansWifiChannelHelper::Default ();

YansWifiPhyHelper phy = YansWifiPhyHelper::Default ();

phy.SetChannel (channel.Create ());

// Configure MAC layer and install devices

WifiMacHelper mac;

Ssid ssid = Ssid (“ns-3-wifi”);

mac.SetType (“ns3::StaWifiMac”, “Ssid”, SsidValue (ssid));

NetDeviceContainer staDevice = wifi.Install (phy, mac, wifiNodes.Get (0)); // STA device

mac.SetType (“ns3::ApWifiMac”, “Ssid”, SsidValue (ssid));

NetDeviceContainer apDevice = wifi.Install (phy, mac, wifiNodes.Get (1)); // AP device

// More configuration and simulation setup code goes here…

Simulator::Run ();

Simulator::Destroy ();

return 0;

}

The specified example is targeted to represent the process of establishment and is simpler. To design and observe the efficiency of WiFi networks in a precise manner, the real simulation situations act as highly difficult aspects which need a thorough configuration of the application traffic, mobility frameworks and network devices.
