Abstract

Un método para sincronizar la transmisión de TDMA de modo directo de un conjunto de radios (Radio A, Radio B) al seguir una radio seleccionada como la líder incluye: recibir, por una radio (Radio A) una comunicación desde otra radio (Radio E), identificar por la radio, una líder de acuerdo con una regla de elección de liderazgo que utiliza la comunicación recibida desde la otra radio y una información líder actual; establecer, por la radio, la líder identificada como su líder, y sincronizar, por la radio, un límite de intervalo de tiempo con un límite de intervalo de tiempo definido por la líder.
