Title
(EN) AN IMPROVED CHANNEL ASSESSMENT SCHEME
(FR) SCHÉMA D'ÉVALUATION DE CANAL AMÉLIORÉ
Abstract
(EN) A source node in a multihop network determines whether to transmit in a channel based on whether the channel is occupied by a packet transmission with a large number of relays; whether the source node is in the data tones back-off zone; and the source node is in the busy tone back-off zone.
(FR) Selon la présente invention, un nœud source dans un réseau multi-bond détermine d'émettre ou non dans un canal sur la base du point de savoir si le canal est occupé ou non par une émission de paquets avec un grand nombre de relais; du point de savoir si le nœud source est dans la zone de réduction de puissance de tonalités de données; et du point de savoir si le nœud source est dans la zone de réduction de puissance de tonalité d'occupation.
