Title
(EN) SOLAR-POWERED ACCESS POINT FOR LOAD BALANCING NETWORK TRAFFIC ACROSS BACKHAUL NETWORKS
(FR) POINT D’ACCÈS À ÉNERGIE SOLAIRE POUR ÉQUILIBRAGE DE CHARGE D’UN TRAFIC DE RÉSEAU PARMI DES RÉSEAUX D’AMENÉE
Abstract
(EN)
A solar-powered device (SPD) node operates as an access point for leaf nodes. The SPD node load balances network traffic received from leaf nodes across different backhaul networks. The SPD node determines a specific backhaul network across which to route the network traffic based on several different factors associated with the SPD node. Those factors include a current battery level, a current solar generation rate, and a current communication link status. The SPD access point also determines the specific backhaul network across which to route the network traffic based on characteristics of the different backhaul networks, including a network latency, among other characteristics.

Un nœud de dispositif à énergie solaire (SPD) fonctionne en tant que point d’accès pour des nœuds feuilles. Le nœud de SPD équilibre la charge d’un trafic de réseau reçu en provenance de nœuds feuilles parmi différents réseaux d’amenée. Le nœud de SPD détermine un réseau d’amenée spécifique, à travers lequel est acheminé le trafic de réseau, sur la base de plusieurs facteurs différents associés au nœud de SPD. Ces facteurs incluent un niveau de batterie actuel, un taux de génération solaire actuel et un état de liaison de communication actuel. Le point d’accès de SPD détermine également le réseau d’amenée spécifique, à travers lequel est acheminé le trafic de réseau, sur la base de caractéristiques des différents réseaux d’amenée, y compris une latence de réseau, parmi d’autres caractéristiques.
