Abstract: 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.
