Simulação de uma Rede WLAN Padrão IEEE 802.11ax Usando o Simulador NS-3

Abstract

This project addresses the simulation of a wireless network standard IEEE 802.11ax operating in infrastructure mode through a network simulation software NS-3 (Network Simulator - 3). The simulation aimed to obtain the data throughput curve in Mbps as a function of the distance between the user terminal and the access point, as a function of the transport protocol used and as a function of variables such as modulation index, guard interval and bandwidth. For this simulation, a code was used that establishes a wireless network with the conditions described, written in C++ language available on the website of the company that developed the NS-3. Through the results obtained, it was found that the throughput does depend on the distance, as long as it is within the coverage area of the wireless network. Furthermore, it was observed that the throughput is strongly influenced by the guard interval between packets, the channel bandwidth and the MCS index that concerns the modulation index and error correction methods.
