    Abstract: In one embodiment, a technique for load balancing of throughput for multi-PHY networks using decision trees is provided. A first device of a mesh communication network may collect at least one transmission metric indicative of a primary link and a secondary link between the first device and a second device of the mesh communication network. The first device may provide the at least one transmission metric as input to one or more decision trees comprising one or more attributes that are each indicative of a threshold for a corresponding transmission metric. The first device may obtain an output from the decision tree comprising a selection of either the primary link or the secondary link. The first device may send, based on the output from the decision tree, one or more packets to the second device using the selected link.

    Abstract: In one embodiment, a device in a mesh network rooted at a root node receives a subroot selection notification. The subroot selection notification indicates that the device should function as a root of a sub-directed acyclic graph (DAG) were a power outage to occur. The device determines that a power outage has occurred. The device forms, after determining that a power outage has occurred, a sub-DAG that is rooted at the device by establishing one or more other devices in the mesh network as routing children of the device in the sub-DAG. The device joins the sub-DAG to a DAG rooted at the root node.

    Abstract: In one embodiment, a method comprises attaching, by a constrained network device in a data network, to a first parent network device in a tree-based storing mode topology in response to receiving a first advertisement message generated by the first parent network device; outputting to the first parent network device a plurality of routes stored in the constrained network device, the routes identifying destinations reachable via the constrained network device; determining, by the constrained network device, that the first parent network device is encountering saturation of stored routes based on the constrained network device receiving a second advertisement message from the first parent network device; and eliminating, by the constrained network device, the saturation encountered by the first parent network device based on moving at least a portion of the routes from the first parent network device to a second parent network device in the tree-based storing mode topology.

    Abstract: Systems, methods, and computer-readable media for identifying a deployment scheme for forming a wireless mesh network based on environmental characteristics and an optimum deployment scheme. In some examples, a geographical area for deployment of a wireless mesh network is identified. Additionally, environmental information of the geographical area can be collected. Network characteristics of an optimum deployment scheme for forming the wireless mesh network can be defined. As follows, a deployment scheme for forming the wireless mesh network can be identified based on the network characteristics of the optimum deployment scheme and the environmental information of the geographical area.
