Title
(EN) USING WATERMARKING TO REDUCE COMMUNICATION OVERHEAD
(FR) UTILISATION DE FILIGRANAGE POUR REDUIRE LA SURCHARGE DE COMMUNICATION
Abstract
(EN)
A method for reducing overhead when transmitting an Internet Protocol (IP) packet begins by selecting a watermarking signature based on the IP address of the packet. The watermarking signature is applied to the packet and the IP address is removed from the packet. The packet is sent to a receiver, which looks up the IP address of the packet by using the watermarking signature. The watermarking signature can be a radio frequency watermarking signature or a digital watermarking signature. A similar method employing watermarking can be used to reduce medium access control header overhead.
(FR)
L'invention concerne un procédé de réduction d'une surcharge lorsque la transmission d'un paquet de protocole Internet (IP) commence par la sélection d'une signature filigranée, basée sur l'adresse IP du paquet. La signature filigranée est appliquée sur le paquet, et l'adresse IP est extraite du paquet. Le paquet est envoyé à un récepteur qui consulte l'adresse IP du paquet au moyen de la signature filigranée. La signature filigranée peut être une signature filigranée de radio-fréquence ou une signature filigranée numérique. Un procédé similaire utilisant le filigranage peut être utilisé pour réduire la surcharge d'en-tête du contrôle d'accès à un support.
