Comunicação por luz visível: redução da latência via combinação de pacotes
Resumo
Espera-se um grande aumento do número de dispositivos conectados à Internet nos próximos anos. A comunicação por luz visível (VLC) está prevista como uma das soluções para a escassez da largura de banda na radiofrequência. O VLC é uma solução para garantir a conexão desse grande números de dispositivos conectados à Internet. Este artigo propõe um protocolo de camada de enlace que utiliza a técnica de codificação de rede, reduzindo a latência, permitindo o uso de frequências mais altas para transmissões. Para os experimentos usou-se o protocolo OpenVLC, um open-source de plataforma VLC definida por software. Os resultados mostram uma significativa redução da latência quando em comparação com os protocolos baseados em solicitação de repetição automática tradicionais.
