Abstract: A method performed by a first node includes determining a routing metric for individual nodes in a set of nodes, receiving a network packet from a second node, selecting a third node in the set of nodes based on the routing metrics, and transmitting the network packet to the third node. The routing metric for a respective one of the set of nodes being based on at least one of a power storage status of the respective one of the set of nodes or a solar power generation status of the respective one of the set of nodes.

Abstract: Various embodiments disclose a method for transmitting data between node devices in a mesh network. The method includes a first node device a channel mask that specifies a set of channels that are available for a channel plan within an operating region associated with the mesh network. The first node device supports a set of channel plans. Based on the channel mask, the first node device determines a set of available channels supported by the first node device. The first node device selects from the set of available channels, at least one channel as a first preferred channel for data transmissions between the first node and a second node included in the mesh network. The first node device configures, based on the first preferred channel, a communication link between the first node device and the second node device.

Abstract: 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.
