    Abstract: In one embodiment, a battery-operated communication device “quick-samples” a frequency hopping sequence at a periodic rate corresponding to a substantially low duty cycle, and is discovered by (e.g., attached to) a main-powered communication device. During a scheduled sample, the main-powered communication device transmits a control packet to be received by the battery-operated communication device, the control packet containing timing information and transmitted to account for worst-case clock drift error between the two devices. The battery-operated communication device responds to the control packet with a link-layer acknowledgment containing timing information from the battery-operated communication device. Accordingly, the two devices may re-synchronize their timing based on the timing information in the control packet and acknowledgment, respectively.

    Abstract: A system and method communicates commands from a command originator to receiving devices, yet the receiving devices do not confirm receipt of the command. The most current command (e.g. the one with the highest sequence number) is rebroadcast by the command originator and the receiving devices, tending to be more frequent upon detection of an event indicating that the most current command was not received by at least one other device, and less frequently upon detection of an event indicating that the most current command was provided with sufficient duplication that if another device could receive it, the device likely did receive it, subject to a maximum and minimum rate.

    Abstract: In one embodiment, a device in a frequency hopping communication network operate in a first mode according to a common broadcast schedule for the network that simultaneously overlays a first configured portion of all independently determined unicast listening schedules in the network. In response to determining a power outage condition, the device switches to operation in a power outage mode where the common broadcast schedule for the network in the power outage mode simultaneously overlays a second configured portion of all independently determined unicast listening schedules in the network, the second configured portion greater than the first configured portion. In one embodiment, the device broadcasts one or more power outage notifications (PONs) in response to determining the power outage condition as a reduction of a main power supply at the device. In another embodiment, the device receives a PON while powered as the power outage condition.

    Abstract: In one embodiment, a communication device samples a particular frequency hopping sequence during only a particular specified sub-timeslot of a timeslot. If a transmission energy is not detected during the specified sub-timeslot, the device turns off its receiver for a remainder of the timeslot. Otherwise, it continues to sample the particular frequency hopping sequence for at least one or more additional sub-timeslots of the remainder of the timeslot. In another embodiment, a communication device determines whether a neighboring communication device is operating in a first mode or a second mode. If in the second mode, it transmits a transmission to the neighboring communication device starting at any sub-timeslot of the plurality of sub-timeslots. If in the first mode, it transmits the transmission to the neighboring communication device while ensuring that the transmission is actively energized during a particular specified sub-timeslot.

    Abstract: In one embodiment, each device in a frequency hopping communication network independently determines its own local unicast listening schedule, and discovers a neighbor unicast listening schedule for each of its neighbors. The devices also synchronize to a common broadcast schedule for the network that simultaneously overlays a configured portion of all unicast listening schedules in the network. Accordingly, the device operate in a receive mode according to their local unicast listening schedule and the common broadcast schedule during the overlaid configured portion, and in a transmit mode according to each neighbor unicast listening schedule and the common broadcast schedule during the overlaid configured portion depending upon a destination of transmitted traffic.
