Abstract

SELEçãO DE ROTA EM REDES SEM FIO. São descritos um Sistema e um método para descobrir uma rota entre um nó de origem e um nó de destino em uma rede sem fio que incluem configurar um sinalizador de resposta intermediário de uma mensagem de solicitação de rota através do nó de origem, inundando a rede sem fio com a mensagem de solicitação de rota e respondendo a esta com a mensagem de resposta de rota através de um primeiro nó intermediário que tem uma rota válida ao nó de destino. Também são descritos um sistema e um método para descobrir uma melhor rota na qual a mensagem de resposta de rota torna-se uma mensagem de resposta de rota. O sistema e o método para descobrir uma melhor rota incluem selecionar através do destino na melhor rota entre ele mesmo e o nó de origem baseado em métricas acumulativas recebidas nas mensagens de solicitação de rota recebidas através do nó de destino, criar uma mensagem de resposta de rota adicional e transmitir a mensagem de resposta de rota adicional ao nó de origem.
