Abstract

La invencion se relaciona con una red inalámbrica con una pluralidad de nodos de red, cada uno de los cuales consiste de al menos un aparato eléctrico y almenos un dispositivo de radio estando dispuestos para intercambiar datos a través de un medioi nalámbrico. Un nodo de red incluye un suministro de reloj parasuministrar todos los aparatos eléctricos y el dispositivo de radio de su reloj. Un nodo de red que es designado como nodo de red principal transmite, através de su dispositivo deradio, u n patron de sincronizacion que depende del reloj de su suministro de reloj. Todos los otros nodos de red, referidos comonodos de red secundarios, son asignados a diferentes clases de distancia jerárquicamente ordenadas dependiendo de sudistancia del nodo de red principal que esasignado para ser la clase de distancia más alta. Todos los nodos de red secundarios de una clase de distancia transmiten, a través de su dispositivo de radiorespectivo, un patron de sincronizacion quedepende del reloj d e su suministro de reloj respectivo y caracteriza la clase de distancia. Un nodo de redsecundario sincroniza su suministro de reloj por medio de al menos un patron de sincronizacion recibido de una clase de distanciajerárquicamente más alta.
