Abstract

"MéTODO E SISTEMA DE REDE SEM FIO". Trata-se de um método de comunicações por uma rede é especialmente adaptado para desempenho de transmissão aperfeiçoado com exigências de largura de banda reduzidas em redes de comunicações que são de baixa qualidade ou têm desempenho de canal físico amplamente variado, por exemplo, redes sem fio (2). O método inclui as etapas de empacotar a carga útil (30) em uma série de pacotes de dados (42), inserir pacotes de cabeçalho (41) no início, meio e em direção ao fim da série, transmitir a série, junto com os pacotes de cabeçalho (41), receber pelo menos algum dos pacotes (42) da série e pelo menos um dos pacotes de cabeçalho (41), e enviar um aviso de recebimento (60). O aviso de recebimento (60) é ou que todos pacotes de dados ou pelo menos um pacote de cabeçalho foi recebido; que nem todos pacotes de dados foram recebidos e pelo menos um pacote de cabeçalho foi recebido; ou que alguns pacotes de dados foram recebidos, mas nenhum pacote de cabeçalho foi recebido. Retransmissões de pacotes de dados e dos pacotes de cabeçalho, quando tais pacotes não são recebidos, são minimizadas a fim de limitar o número de comunicações necessárias para distribuir uma carga útil de dados completa.
