Abstract

MéTODO PARA CONTROLE DE ACESSO DE MEIO DESCENTRALIZADO EM UMA REDE DE COMU NICAçãOES, REDE DE COMUNICAçõES E, DISPOSITIVO SEM FIO Um sistema (400), dispositivo (401), e método, são providos para controle de acesso de meio descentralizado, compreendendo balizamento periódico (600), transmissões de todos os dispositivos ativos em aberturas de balizamento (204) (302) (303), agrupamento de tais aberturas de balizamento (204) (302) (303) em pelo menos um período de balizamento dinâmico contíguo (301), e expandir ou contrair este pelo menos um período de balizamento dinâmico contíguo (301), dependendo do número de aberturas de balizamento ocupadas (204) (302) ( 303). Péríodo de balizamento dinâmico (301) se adapta a dispositivos (401) incorporando-se e deixando a rede (400), bem como a colisões de quadros de balizamento (600) no meio (410).
