Abstract

o propósito da presente invenção é aumentar a precisão de sincronismo de tempo entre uma pluralidade de dispositivos sem fio em uma rede sem fio. uma unidade de processamento de sincronismo de tempo realiza um processo de sincronismo de tempo entre um dispositivo e um outro dispositivo da rede sem fio. uma unidade de determinação de mestre/escravo determina se o dispositivo é um dispositivo mestre ou um dispositivo escravo na rede sem fio. a unidade de processamento de sincronismo de tempo realiza o processo de sincronismo de tempo como um relógio mestre em relação a um dispositivo escravo subordinado se o dispositivo for um dispositivo mestre, ou realiza o processo de sincronismo de tempo como um relógio escravo em relação a um dispositivo mestre se o dispositivo for um dispositivo escravo.
