Análise do Atraso na Transmissão de Pacotes em Redes WiMAX utilizando o NS-3
Abstract
This paper presents a study evaluating the delay in packets transmission to PMP (Point-to-Multipoint) topology in WiMAX networks. To analyze the delay in packet transmission we considered different modulation formats: BPSK (Binary Phase Shift Keying), QPSK (Quadrature Phase Shift Keying) and QAM (Quadrature Amplitude Modulation), and for the QoS (Quality of Service) class: UGS (Unsolicited Grant Service), RTPS (Real-Time Polling Service), NRTPS (Non-Real-Time Polling Service) and BE (Best Effort). For the realization of the simulations, the NS-3 (Network Simulator - version 3) was used. In terms of modulation format, the results show that QAM64 34 compared to BPSK 12 showed a lower delay time between packets of 89.96%, or 16.91 ms (milliseconds). In terms of QoS class, the UGS showed a minimum delay time between packets of 123.61% or 10.38 ms.
