Arquitetura com Suporte à Predição de QoEe Mobilidade para Aplicações de Vídeo em Redes Sem Fio Heterogêneas
Resumo
Este artigo propõe uma arquitetura para redes da próxima geração capaz de fornecer acesso heterogêneo sem fio e handover transparente para as aplicações de vídeo. A proposta considera diferentes tecnologias sem fio e adota o padrão IEEE 802.21 para auxiliar na integração de redes heterogêneas. A Arquitetura proposta denominada de QoEHand (Qualityof Experience Handover) apresenta mecanismos de predição de Qualidade de Experiência baseada em Redes Neurais Artificiais que será o parâmetro a decisão de handover, e mecanismo de descarte seletivo de pacotes especifico para aplicações multimídia. A proposta é avaliada via simulação utilizando-se o ns-2 (Network Simulator) e os resultados de desempenho são apresentados através das métricas de QoE.
