Title: ON-DEMAND PAIR-WISE FREQUENCY-HOPPING SYNCHRONIZATION
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.
