    Abstract: Various embodiments disclose a method comprising receiving, at a first node, a listening schedule associated with a second node; determining, by the first node, a link latency associated with the second node based on the listening schedule; in response to the first node detecting a frame transmission failure for a frame being transmitted by the first node to the second node, determining, by the first node based on the link latency, a backoff time; and in response to the first node determining that the backoff time has elapsed, the first node retransmitting the frame from the first node to the second node. In some embodiments, the method also includes determining a frame lifetime value associated with the second node based on the link latency; and in response to determining that a time period corresponding to the frame lifetime value has elapsed, dropping the frame.

    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.

    Abstract: Techniques for implementing a network protocol for battery-powered devices (BPDs) include a method performed by a BPD node comprising identifying one or more first potential parent nodes in a BPD subtree within a wireless network; selecting a first parent node from the one or more of first potential parent nodes; transmitting, to a root BPD node of the BPD subtree, a first request to join to the BPD subtree via the first parent node, the root BPD node connecting the BPD subtree to a main network, wherein the BPD subtree is managed according to a first set of subtree parameters different from a second set of subtree parameters for subtrees of the main network; receiving, by the BPD node, a response to the first request from the first parent node; and determining, based on the response, whether to connect to the BPD subtree through the first parent node.

    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.
