NDIST - Um Mecanismo de Filtragem de RSSI Eficiente para Algoritmos de Handoff em Redes Densas
Resumo
Em redes sem fio densas, handoffs são comuns. Os critérios para acioná-los não são definidos pelo padrão IEEE 802.11, sendo específicos para a implementação de cada fabricante. Implementações atuais de handoff geralmente usam o RSSI (Indicador de Intensidade do Sinal Recebido) como métrica de desempenho e, comumente, causam instabilidade na associação, um problema conhecido como o efeito ping-pong. Para prevenir este efeito, será proposto o NDIST, um mecanismo de filtragem de RSSI, cujo objetivo é aumentar a estabilidade de associação ocasionando baixo atraso no acionamento do handoff. Testes comparativos demonstram que o NDIST melhora a estabilidade sem gerar aumento expressivo do atraso.Referências
