Abstract

UN SISTEMA DE COMUNICACION ALOHA RANURADO DE LONGITUD DE ESTRUCTURA DINAMICA TIENE UNA ESTACION CENTRAL QUE VIGILA LA CONGESTION DE TRAFICO Y DETERMINA LA LONGITUD OPTIMA DE LA ESTRUCTURA. ESTO SE TRANSMITE A SUBESTACIONES EN LA FORMA DE UN MENSAJE DE INFORMACION DE SERVICIO CUANDO NO TIENE QUE HABER UN CAMBIO EN LA LONGITUD DE LA ESTRUCTURA PERO NO, COMO ES CONVENCIONAL, EN EL PRINCIPIO DE CADA ESTRUCTURA. LA CANTIDAD DE TIEMPO NECESARIO PARA LA TRANSMISION UTIL DE MENSAJES DE COMUNICACION SE OPTIMIZA DE ESTA MANERA.
