Resumo


A arquitetura C-RAN (Centralized Radio Access Network) é uma proposta para atender à alta demanda das redes de quinta geração (5G). Devido o tráfego de comunicação possuir um comportamento dinâmico em decorrência do “Efeito de Maré” (fenômeno responsável pela movimentação do fluxo de rede), a arquitetura atual, o D-RAN (Decentralized Radio Access Network) não garante o fornecimento eficiente de recursos. Este trabalho apresenta uma heurı́stica para o dimensionamento de recursos de hardware considerando o Número de Usuários Atendidos e Vazão Agregada. A abordagem atendeu a variabilidade do tráfego, maximizando a eficiência da BBU (BaseBand Unit) e quantificando as SC’s (Small Cells) necessárias para cobrir a demanda da rede.

Palavras-chave: C-RAN, Efeito de Maré, 5G, Heurística
