Abstract

"MéTODO DE ACESSO SELETIVO PARA CANALCOMPARTILHADO EM CIRCUITO EMISSOR-RECEPTOR DECOMUNICAçãO SEM FIO". Cada estação remota em uma célulade rede sem fio que utiliza um esquema de acesso múltiploorientado por colisão, conta o número de novas tentativas feitaspara obter acesso à estação de base para uma mensagemespecífica. O valor acumulado do número de novas tentativas éentão inserido em um campo de contagem de novas tentativas damensagem de solicitação de acesso. Após uma ou mais novastentativas, a estação de base recebe de forma bem-sucedida amensagem de solicitação de acesso. A estação de base executaum programa gerenciador de alocação de canal de acesso comumque proporciona adaptativamente canais adicionais para a estaçãoremota, dependendo do número de novas tentativas que aestação remota exigiu para transmitir de forma bem-sucedida amensagem de solicitação de acesso. Desta maneira, a estação debase tem informação precisa sobre o desempenho reduzido que asestações remotas sofrem durante um intervalo de elevadautilização, para permitir que a estação de base proporcioneadaptativamente canais adicionais para as estações remotas.
