Abstract

método de comunicação. alguns protocolos para a transmissão de dados em uma rede de comunicação, como o protocolo lorawan, usam quadros que compreendem cargas úteis destinadas a transportar dados úteis, cujo tamanho pode variar de um quadro para outro. um método de comunicação é proposto para transmitir dados nesse tipo de rede. esse método é baseado na divisão de um pacote de carga útil em um conjunto de blocos e, em seguida, na inserção dos blocos formados em pelo menos um segmento. cada segmento compreende um número de blocos adequados para um tamanho de carga útil no momento da criação do segmento. os segmentos são complementados a seguir com informações de verificação, permitindo que um destinatário do referido pacote de dados determine se recebeu todos os blocos. no caso de não recepção de todos os blocos, o remetente dos referidos blocos retransmite pelo menos os blocos não recebidos.
