Abstract: In one embodiment, a transmitting device may determine a first data frame to a first destination and a second data frame to a second destination, and may assign subcarriers in a non-overlapping arrangement to the first and second data frames. Once assigned, the transmitting device may augment a transmission physical (PHY) header with a destination and tone map tuple for each of the first and second destinations, and transmits the transmission with the first and second data frames simultaneously on the assigned subcarriers.

Abstract: In one embodiment, a device determines a set of sources and used destinations for traffic in a computer network, where nodes of the network are configured to send all traffic to the used destinations through a root node of the computer network according to a directed acyclic graph (DAG). The device may then also determine a set of capable nodes as common ancestors to source-destination pairs that provide a more optimal path between the source-destination pairs than traversing the root node, and instructs the set of capable nodes to store downward routes to forward traffic for one or more of the used destinations according to the stored downward route rather than through the root node.

Abstract: In one embodiment, a region anchor node may receive a unicasted route request (RREQ) for a target node. The region anchor node may then flood the RREQ to a region within which it resides. Subsequently, the region anchor node may receive one or more reactive routing route replies (RREPs) returned by the target node within the region. Based on the RREPs, the region anchor node may build one or more region routes from the region anchor node to the target node, and returns the one or more region routes to the originator node to cause the originator node to concatenate the one or more region routes and the unicast route of the original RREQ to form a path from the originator node to the target node.

Abstract: In one embodiment, a transmitting device monitors transmission activity of each of a plurality of subcarriers in a communication network, and determines a set of unutilized subcarriers of the plurality of subcarriers. As such, the transmitting device may then transmit a data frame on one or more of the unutilized subcarriers to a receiving device while transmission activity is present on one or more utilized subcarriers within the network. In another embodiment, the transmitting device may also determine timing information associated with the transmission activity, and may correspondingly schedule the transmitting to optimize network performance based on the timing information.

Abstract: In a multiple interface, low power and lossy network comprising a plurality of nodes, a low transmission power and medium transmission power topology are defined for the network and a channel-hopping schedule is defined for the devices operating in each topology. A mixed channel-hopping sequence comprising an interleaved low- power channel hopping sequence and a medium-power channel hopping sequence is generated, such that a single device in the network may allow neighboring devices in the network to use both low-power and medium-power channels to communicate with the single device.

Abstract: In one embodiment, a device maintains a predetermined number of high- priority subcarriers for use in communicating high-priority data frames and a predetermined number of low-priority subcarriers for use in communicating low- priority data frames. A data frame is received and a data frame priority is determined for the data frame. If the data frame is determined to be a low-priority data frame, a minimum number of subcarriers, from the low-priority subcarriers, required for communication of the data frame is determined and the data frame is communicated using the minimum number of subcarriers. If the data frame is determined to be a high-priority data frame, a maximum number of subcarriers available, including the high-priority subcarriers and the low-priority subcarriers, is determined and the data frame is communicated using the maximum number of subcarriers.

Abstract: In one embodiment, a device receives and stores a broadcast schedule, and may determine whether a neighbor unicast listening schedule is available for a neighboring device. If so, the device may transmit a data frame to the neighboring device pursuant to the neighbor unicast listening schedule. If a neighbor unicast listening schedule is not available, the device may transmit the data frame to the neighboring device pursuant to a broadcast schedule. Once the data frame is received by the neighboring device, pursuant to the neighbor unicast listening schedule or the broadcast schedule, an acknowledgement may be received from the neighboring device, which may include an updated neighbor unicast listening schedule for that neighboring device.

Abstract: In one embodiment, a device determines a need to resynchronize a broadcast and unicast frequency-hopping schedules on its network interface. In response to the need, the device may solicit the broadcast schedule from one or more neighbor devices having the synchronized broadcast schedule, and then establishes the unicast schedule for the network interface using communication during the synchronized broadcast schedule.
