    Abstract: In one embodiment, a device in a network determines a first channel hopping schedule for the device to receive unicast communications from one or more neighbors of the device. The first channel hopping schedule differs from channel hopping schedules used by the one or more neighbors to receive unicast communications. The device determines a second channel hopping schedule for the device that includes a common channel that is common to the device and the one or more neighbors at any given point in time, wherein the second channel hopping schedule is self-generated by each of the device and the one or more neighbors. The device switches from the first channel hopping schedule to the second channel hopping schedule, in response to a network event. The device causes a particular neighbor to join the network using the second channel hopping schedule.

    Abstract: According to one embodiment, techniques are provided to enable secure communication among devices in a mesh network using a group temporal key. An authenticator device associated with a mesh network stores a pairwise master key for each of a plurality of devices in a mesh network upon authentication of the respective devices. Using the pairwise master key, the authenticator device initiates a handshake procedure with a particular device in the mesh network to mutually derive a pairwise temporal key from the pairwise master key. The authenticator device encrypts and signs a group temporal key using the pairwise temporal key for the particular device and sends the group temporal key encrypted and signed with the pairwise temporal key to the particular device.

    Abstract: In one embodiment, a device in a network determines that one or more network nodes should use a stateful address configuration protocol to obtain network addresses. The device causes the one or more network nodes to use the stateful address configuration protocol, in response to determining that the one or more nodes should use the stateful address configuration protocol to obtain network addresses. The device determines that the one or more network nodes should use a stateless address configuration protocol to obtain network addresses. The device causes the one or more network nodes to use the stateless address configuration protocol, in response to determining that the one or more nodes should use the stateless address configuration protocol to obtain network address.

    Abstract: In one embodiment, a device that is protected against a power outage event in a network receives metrics used by a first node in the network to select a routing link to a second node in the network. The device stores the metrics used by the first node to select the routing link to the second node. The device selects a set of one or more of the metrics to provide to the first node during network formation after a power outage event in the network. The device provides the selected set of one or more of the metrics to the first node, wherein the first node uses the provided set to reestablish connectivity to the network.
