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: A node within a wireless network is powered by a solar hybrid battery system. The solar hybrid battery system includes a solar panel, a primary cell, and a secondary cell. The secondary cell includes only enough power storage to be capable of powering the node during the longest daily interval of darkness in the region where the node is deployed. The solar panel is sized relative to the secondary cell to be capable of fully recharging the secondary cell during the shortest daily interval of daylight in the region where the node is deployed, even under conditions of limited solar irradiance (e.g. due to clouds). The primary cell can charge the secondary battery if the node is shelved or malfunctioning to prevent the secondary cell from becoming overly depleted. The primary cell can also provide the node with additional power during times of peak demand or to perform status reports.

Abstract: A network device for installation at a geographic location includes a rechargeable power cell configured to store a first amount of energy sufficient to power the network device during a longest night of a year at the geographic location without the rechargeable power cell being fully depleted and a solar panel configured to generate a second amount of energy sufficient to, during any given cloudy day at the geographic location, power the network device and fully recharge the rechargeable power cell.

Abstract: Various embodiments set forth a method comprising determining, by a first computing device powered by a rechargeable battery and a non-rechargeable battery, whether to change operation of the first computing device from a first operating state to a second operating state based on one or more of a state of the rechargeable battery, a state of the non-rechargeable battery, or a state of a communication mode of the first computing device; and in response to determining that operation of the first computing device should change to the second operating state, increasing, by the first computing device, an interval between communications with one or more second computing devices using the communication mode.

Abstract: Techniques for a low latency hybrid network include storing, at a first node, metrology data received from a second node via a communication link of a first type; establishing, by the first node at a scheduled time, a connection to a server via a communication link of a second type, wherein the second type is different from the first type; and transmitting, by the first node, the metrology data to the server via the communication link of the second type.

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.

Abstract: A method performed by a first node includes determining respective routing metrics for individual nodes in a set of nodes, wherein higher values for a respective routing metric for a respective node of the set of nodes indicate a higher suitability for forwarding network traffic using the respective node of the set of nodes; receiving a first network packet; in response to determining that the first network packet is a low priority packet, selecting a second node from the set of nodes based on the second node having a respective routing metric below a threshold value; and forwarding the first network packet to the second node.

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.
