Abstract

EL DISPOSITIVO UTILIZA UN ESTADO DE TRANSMISION EN COLAS DENTRO DE UNA CAPACIDAD DE CANAL DE INFORMACION DE PEQUEÑA FRACCION, GRACIAS A UN CIRCUITO PARA MEDIR LA DISTANCIA DESDE CADA TERMINAL AL CENTRO PRINCIPAL, LO CUAL PERMITE SINCRONIZAR LA TRANSMISION DE ESTADO EN COLAS MINIMIZANDO LA OCUPACION FISICA DE CANAL DE TRANSMISION, EL RETRASO DE COLA PARA ACCEDER A LA RED ES GOBERNADA POR UN ALGORITMO DE ACCESO, PROCESADO POR EL MISMO DISPOSITIVO, EL CUAL ES PROVISTO EN CADA TERMINAL DE LA RED.
