Abstract: 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.

Abstract: One embodiment of the present invention sets forth techniques for processing packets transmitted within a network in accordance with a network protocol. The techniques include receiving, by a network device in a mesh network, a type-length-value (TLV) element; determining, by the network device based on both a first type identified in a type field of the TLV element and a value in at least one sub-field of a value field of the TLV element, an expected length of the value field of the TLV element; and processing, by the network device, the value field up to the expected length.

Abstract: 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.

Abstract: A wireless network includes nodes configured to implement an improved parent and path selection process to efficiently and reliably manage energy consumption of a battery powered device node. When a given node selects a path, the node transmits requests to multiple potential parent nodes. Each potential parent node transmits a metric that is indicative of the remaining battery life of the nodes in the path that includes the respective potential parent node. The given node then selects a parent node, and corresponding path, based on the metrics. More specifically, the given node selects a path, where at least one node on the selected path is less likely to prematurely exhaust the remaining battery life of the node, relative to the nodes in the other potential paths. As a result, the given node selects a path that optimizes battery consumption of the various battery powered nodes in the wireless network.

Abstract: A wireless mesh network includes a child node coupled to a parent node. The parent node transmits time sync beacons that indicate a time slot number and a start time for a current time slot. The child node receives the time sync beacons and determines a delta between the current time slot number of the child node and the current time slot number of the parent node. The child node also computes an offset between a start time of the current slot of the child node and the start time of the current slot of the parent node. The child node reports the delta and the offset to the parent node. Based on the delta and the offset, the parent node determines when, and on what channel, the child node is predicted to be receiving transmissions, and then schedules transmissions to the child node accordingly.

Abstract: 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 determining a first expected length of a value field included in a type-length-value (TLV) element within a first frame of a first packet received over the network, wherein the first expected length is based on a type field included in the TLV element. The technique also includes processing a first portion of the value field based on the expected length of the value field in accordance with a first specification for a first version of the network protocol, without processing a second portion of the value field beyond the expected length of the value field.

Abstract: A wireless network includes a plurality of nodes configured to implement an improved discovery process to efficiently and reliably pair with one another with low power consumption. A given node divides time into slots and then performs discovery operations during designated discovery windows. The discovery windows occur periodically but at different times of day. During a given discovery window, nodes attempt discovery using a reduced set of channels that varies from one window to the next, thereby increasing the likelihood that nodes operate on the same channel. Nodes also implement a pairing protocol to coordinate pairing, potentially avoiding situations where all nodes attempt to pair simultaneously. The discovery process may be completed expeditiously, thereby conserving power and extending the operational lifetime of nodes which rely on battery power.
