    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 translation: 在一个实施例中，通信设备仅在时隙的特定指定子时隙中采样特定的跳频序列。 如果在指定的子时隙期间未检测到传输能量，则该设备在时隙的剩余时间内关闭其接收机。 否则，它继续针对时隙的其余部分的至少一个或多个附加子时隙对特定跳频序列进行采样。 在另一个实施例中，通信设备确定相邻通信设备是否在第一模式或第二模式中操作。 如果在第二模式中，则从多个子时隙的任何子时隙开始向相邻通信设备发送传输。 如果在第一模式中，则将传输发送到相邻通信设备，同时确保在特定指定子时隙期间传输被激活。

    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.

    Abstract: In one embodiment, a transmitter in a communication network receives an indication of active transmission times of a receiver to which the transmitter attempts to reach with first transmissions, the active transmission times indicating respective times of second transmissions initiated by the receiver. Based on determining when the first transmissions occur, the transmitter may then compute a link reliability metric for a link from the transmitter to the receiver by excluding one or more of the first transmissions from the indicated active transmission times of the second transmissions. In one embodiment, the active transmission times are in the past and the reliability metric excludes any first transmissions in the past during those times, while in another embodiment the active transmission times are scheduled in the future and the reliability metric does not include any first transmissions since the first transmissions may be scheduled to avoid the active transmission times.

    Abstract: A system and method stores wirelessly received communications for wireless retransmission, making space in a storage device, if necessary, by deleting any one or more communications corresponding to the same group as the received communication. If storage in the storage device remains insufficient, communications that have been previously retransmitted by that same device are deleted, according to one or more characteristics of such stored communications, such as age or number of times an instance of that communication has been received. If storage in the storage device remains insufficient, communications of a different group are deleted according to one or more characteristics of the stored communications.

    Abstract: Techniques are provided for adaptive routing of authentication packets in a network, such as a wireless mesh network. At an authenticated device in the network, an authentication packet is received over the network from a device that is seeking authentication. The authentication packet is encapsulated for transmission in Layer 3 packets over an Internet Protocol (IP) tunnel to an authenticator device associated in the network. Similarly, for an authentication packet encapsulated in Layer 3 packets from the authenticator device over the IP tunnel, the authentication packet is decapsulated from the Layer 3 packets and transmitted over the network to the device seeking authentication.

    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.
