The step-by-step procedure for building a simple wireless LAN

In this section, we are going to learn how to set up a simple wireless LAN with 1 Wi-Fi AP and 20 Wi-Fi STAs by doing the following:

1. Set the Wi-Fi standard as 802.11ac.
2. Set up a Wi-Fi AP with the SSID Packt.
3. Set up 20 Wi-Fi STAs.
4. Randomly place the 20 Wi-Fi STAs around the AP within a radius of 30 meters.
5. Allow all STAs to move around the AP.
6. Test the connectivity between all STAs and the AP.
7. Test the link speed between an STA and the AP.

Let’s write the following code snippets in simple_wifi_lan.cc to simulate a simple wireless LAN.

First import all the necessary ns-3 packages:

#include "ns3/core-module.h"
#include "ns3/yans-wifi-helper.h"
#include "ns3/yans-wifi-channel.h"
#include "ns3/ssid.h"
#include "ns3/mobility-helper.h"
#include "ns3/internet-module.h"
#include "ns3/internet-apps-module.h"
#include...
