Abstract

Varrimento de vizinhos em redes de área local sem fio. Método de varrimento de vizinhos em rede de área local sem fio que contém uma estação, primeiro ponto de acesso (AP) ao qual a estação está associada e segundo AP inicia-se por meio da geração de informações de tempo referentes a sinal de farol enviado pelo segundo AP. As informações de tempo são relatadas pelo primeiro AP para a estação. A estação programa tempo, com base nas informações de tempo, para ouvir o sinal de farol transmitido pelo segundo AP.
