摘要： One embodiment of the present invention sets forth a technique for processing packets transmitted within a network in accordance with a network protocol. The technique includes a network device in a mesh network receiving a type-length-value (TLV) element, determining, based on a type field of the TLV element, an expected length of a value field of the TLV element, and processing the value field up to the expected length.

摘要： Techniques for path selection in a network include a first node in a mesh network receiving, from a second node in the mesh network, a first battery life metric for a path through the mesh network, determining a value representing a remaining battery life of the first node, calculating a second battery life metric based on at least one of the first battery life metric for the path or the value representing the remaining battery life for the first node, and transmitting, to a third node in the mesh network, the second battery life metric.

摘要： Techniques for discovering a device in a wireless network are described herein. For example, a first device may send a network discovery solicitation message to a second device to solicit a communication relationship (e.g., request connection to a parent). The network discovery solicitation may include one or more information elements that indicate a channel function associated with the first device and a listening window during which the first device will be listening for communications. The second device may use the channel function to frequency hop and send a network discovery message to the first device during the listening window. The network discovery message may include one or more information elements to establish a sampled schedule for the first device moving forward.

摘要： A wireless mesh network includes a plurality of nodes coupled together in parent-child relationships. A child node is configured to cascade listening rate changes upstream to a parent node to perform low-latency communications. The child node transmits an authentication message to the parent node indicating the listening rate change. The child node sets a timer and waits for an acknowledgement from the parent node. If the child node receives the acknowledgement, then the child node and the parent node change listening rate to permit low-latency communications. In addition, if the parent node loses network access, the parent node sets a timer and then waits to abandon the child node until after the timer elapses.

摘要： Techniques for communicating schedule data regarding a schedule are described herein. For example, a device may communicate a schedule information element that includes a tag indicating a first operating context to which to apply schedule data regarding a schedule. The schedule information element may also include a reference tag to indicate whether the schedule data is contained in the schedule information element or has been previously received and/or to identify a second operating context associated with previously received schedule data. If the reference tag indicates that the schedule data is contained in the schedule information element, the schedule data may be extracted from the schedule information element and applied to the first operating context. If the reference tag indicates that the schedule data has been previously received, the previously received schedule data may be accessed and applied to the first operating context.

摘要： Techniques for allocating event offsets within a period of transmission are described. A mains-powered device (MPD) may act as a “parent” to one or more battery-powered devices (BPDs). The MPD may assign “event offsets” to each BPD. The event offset is a time by which the BPD's timeslot is “offset” from the start of a periodic cycle of transmissions by the MPD. Thus, each event offset indicates a time that the BPD must be “awake,” i.e., operating its radio receiver and/or performing other functionality. A BPD may spend a substantial fraction of its time in a “sleep” mode, wherein less power is used and fewer functions are performed than during a period of that BPD's event offset. Another BPD may have a different event offset. Communications by the MPD with each child BPD may be substantially uniformly distributed over the period. To increase efficiency, groups of BPDs may receive multicasts.

摘要： Techniques for acknowledging communications from multiple devices are described herein. For example, a device may broadcast a group acknowledgement message indicating that communications from multiple devices have been received by the device. Each acknowledgement in the group acknowledgement message may include a device identifier for a device that sent a communication (e.g., a Medium Access Control (MAC) address of the device, a hash of the MAC address of the device, etc.) and a communication identifier for the communication (e.g., a sequence number of the communication, a Cyclic Redundancy Check (CRC) code for the communication, etc.).

摘要： Disclosed are techniques to minimize the electricity consumption of battery powered devices during network discovery and other phases of network operation. Example techniques include efficiently listening for other mains powered and battery powered devices within communication range of the battery powered device by, for example, shortening its listening window depending on how close the time reference maintained by the battery powered device is estimated to be to the time reference used by the other mains powered and battery powered devices within communication range. Other techniques include slowing the rate of listening by the battery powered device when the battery powered device is unlikely to be able to receive discovery messages or is already connected to the network. Other techniques include using knowledge of the network to listen for discovery messages on a channel or channels on which other devices are likely to be transmitting.
