First Claim
1. A method, comprising:
- receiving a broadcast schedule and storing the broadcast schedule in a memory;
determining, using a processor, if a neighbor unicast listening schedule is available for a neighboring device;
when the neighbor unicast listening schedule is available, transmitting a data frame to the neighboring device pursuant to the neighbor unicast listening schedule; and
when the neighbor unicast listening schedule is not available, transmitting the data frame to the neighboring device pursuant to the broadcast schedule.

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.

17. A tangible non-transitory computer-readable storage medium having computer-executable instructions stored thereon that, when executed by a processor, cause the processor to perform operations comprising:
-
determining a local unicast listening schedule and storing the local unicast listening schedule in a memory; receiving a broadcast schedule and storing the broadcast schedule in the memory; receiving a first data frame pursuant to the broadcast schedule and, in response to receipt of the first data frame, transmitting a first acknowledgement message, the acknowledgement message including the local unicast listening schedule; determining if a neighbor unicast listening schedule is available for a neighboring device; when the neighbor unicast listening schedule is available, transmitting a second data frame to the neighboring device pursuant to the neighbor unicast listening schedule; and when the neighbor unicast listening schedule is not available, transmitting the second data frame to the neighboring device pursuant to the broadcast schedule. - View Dependent Claims (18, 19, 20)
