Otimização de Retardo na Alocação de Recursos em Redes Sem Fio f-OFDM com Agregação de Subportadoras
Resumo
Neste artigo, propomos um esquema de alocação de recursos em redes sem fio com o objetivo de otimizar o retardo de dados dos usuários. O desempenho do algoritmo de alocação de recursos é verificado e comparado com outros da literatura utilizando simulações computacionais em termos de vários parâmetros de QoS como índice de justiça, vazão e taxa de perda. Nestas simulações, consideramos também técnicas atuais e candidatasás redes da próxima geração como agregação de portadora e f-OFDM com intuito de mostrar que é possível prover maior taxa de transmissão e menor latência em relaçãoás redes 4G.
