Abstract

"SISTEMA E MéTODOS PARA PROGRAMAçãO DE PACOTE DISTRIBUìDA, E, MéTODOS PARA COMPRESSãO DE UMA PLURALIDADE DE ENTRADAS DE VIZINHO EM UMA LISTA DE VIZINHANçA CONTIDA EM UM PACOTE DE CONFIGURAçãO DE REDE, PARA TRANSMISSãO DE UM PACOTE DE CONFIGURAçãO DE REDE ASSOCIADO COM UM Nó EM UMA REDE AD HOC, E PARA PROGRAMAçãO DE TRANSMISSãO EM UMA REDE AD HOC". A presente invenção provê um protocolo de controle de acesso de meio (MAC) para a transmissão livre de colisão de pacotes em um canal, tal que aos nós sejam designados intervalos de tempo para transmissão livre de colisão baseados no conhecimento que eles adquirem relativo a clientela de suas vizinhanças locais e dos anúncios dos intervalos de tempo quando os nós em vizinhanças locais tentarão transmitir novamente. O procedimento de programação pode utilizar uma idade da rede junto com os identificadores únicos de nós. Os tempos de transmissão de candidato para cada nó são determinados usando uma lista dos tempos de transmissão subseq³entes anunciados por outros nós. Os nós descartam os tempos de transmissão anunciados da lista de tempos de transmissão potenciais, e computa seus tempos de transmissão de candidato usando uma função que provê uma distribuição variada (pseudo-aleatória) de saídas para uma amostra variada de entradas. Esta função pode ser uma função de reedição, uma função de criptografia, ou uma função de tabela de consulta. A computação de tempos de transmissão de candidato usa os identificadores daqueles nós para os quais nenhum tempo de transmissão anunciado foi obtido.
