Abstract: In one embodiment, network parameters are dynamically adjusted using weather forecasts. The embodiments include determining a weather forecast that predicts a weather condition proximate to a network. Network parameters are then selected for adjustment based on the predicted weather condition. The selected network parameters are adjusted to improve performance of the network in response to the predicted weather condition.

Abstract: In one embodiment, a first node in a shared-media communication network may receive a message indicated a scheduled downtime of a second node located between the first node and a destination. The first node may determine whether to perform a search for an alternate route toward the destination. In response to determining to perform the search, the first node may perform the search for an alternate route toward the destination for use at least during the scheduled downtime.

Abstract: In one embodiment, a client device determines when it is coupled to an IoT/LLN device to establish and enable an IP link between a headset interface on the client device and a signal interface on the IoT/LLN device. Once the IP link is established, a duplex data signal is transmitted between the client device and the IoT/LLN device, via the IP link.

Abstract: In one embodiment, a device receives a destination unreachable message originated by a particular node along a first source route, the message carrying an encapsulated packet as received by the particular node. In response, the device may determine a failed link along the first source route based on a tunnel header and the particular node. Once determining an alternate source route without the failed link, the device may re-encapsulate and re-transmit the original packet on an alternate source route with a new tunnel header indicating the alternate source route (e.g., and a new hop limit count for the tunnel header and an adjusted hop limit count in the original packet).

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: In one embodiment, a device identifies inter-personal area network (PAN) traffic between a first PAN and a second PAN. The device identifies a network node in the first PAN associated with the inter-PAN traffic and determines that the network node should join the second PAN. The device causes the network node to join the second PAN, in response to determining that the network node should join the second PAN.

Abstract: Utilizing multiple network interfaces when sending data and acknowledgement packages comprises, in a low power and lossy network (LLN) or other network, a sender device comprises two or more network interfaces for communicating with one or more recipient devices. The sender device assesses the transmission capabilities of the network interfaces to determine data rates available for each interface. The sender device specifies which network interface will be used to transfer data and which network interface will be used to receive an acknowledgement from the recipient device. The sender device selects the network interface with the larger data capacity for transmitting a data packet and the network interface with the smaller data capacity for receiving an acknowledgement. The data transmission and the acknowledgement transmission may be transmitted simultaneously. The recipient device uses transmission parameters received from the sender device to determine the data rate with which to transmit the acknowledgement.

Abstract: In one embodiment, data packet messages are received in a Field Area Router (FAR) sent from one or more sources toward one or more destination devices in a Low-Power Lossy Network (LLN). An LLN routing topology for the data packet messages is interpolated in the FAR. An expected time for the data packet messages to reach a destination device in the LLN is determined based upon the routing topology interpolation. Traffic shaping is applied by the FAR for the data packet messages based upon the determined expected time for the data packet messages to reach destination devices in the LLN.

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.
