Title

Abstract
(EN)
A solar-powered device (SPD) relay node is coupled to a remotely-located "leaf" node in order to provide the leaf node with network access. The SPD relay node routes network traffic to and from the leaf node via one or more different paths that traverse other SPD relay nodes that reside upstream of the SPD relay node. The SPD relay node determines a specific path across which to route the network traffic based on several different factors associated with the upstream SPD relay nodes, including battery level, solar generation rate, and link quality. The SPD relay node generates a routing metric for each upstream SPD relay node based on these different factors and then routes traffic across the upstream SPD relay nodes based on the routing metric and based on a priority level associated with the network traffic.

L'invention concerne un nœud relais de dispositif à énergie solaire (SPD) qui est couplé à un nœud "feuille" situé à distance afin de fournir un accès au réseau au nœud feuille. Le nœud relais de SPD achemine le trafic de réseau vers le nœud feuille, et à partir de ce dernier, par le biais d'un ou de plusieurs trajets différents qui traversent d'autres nœuds relais de SPD qui résident en amont du nœud relais de SPD. Le nœud relais de SPD détermine un trajet spécifique par lequel acheminer le trafic de réseau sur la base de plusieurs facteurs différents associés aux nœuds relais de SPD en amont, comprenant le niveau de batterie, le taux de génération d'énergie solaire et la qualité de liaison. Le nœud relais de SPD génère une mesure de routage pour chaque nœud relais de SPD en amont sur la base de ces différents facteurs, puis achemine le trafic sur les nœuds relais de SPD en amont sur la base de la mesure de routage et sur la base d'un niveau de priorité associé au trafic de réseau.
