摘要： Targeted parent selection for nodes within a network include, filtering, by a node in a mesh network using one or more first network optimization criteria, a set of potential parent nodes to generate a subset of potential parent nodes; selecting, by the node using one or more second network optimization criteria, a target parent node from the subset of potential parent nodes; and transmitting, by the node, a connection request to the target parent node.

摘要： A network system includes a main network implementing a conventional network protocol and a BPD subtree implementing a custom network protocol. The main network comprises a plurality of MPD nodes, the conventional network protocol being configured for MPD nodes. The BPD subtree comprises a plurality of BPD nodes, the custom network protocol being configured for BPD nodes. The custom network protocol defines smaller and simpler subtrees relative to the conventional network protocol. As a result, the custom network protocol defines less complex functions relative to the conventional network protocol, including functions for discovery, messaging, and loop management. A root node of the BPD subtree is connected with an MPD node of the main network and one or more descendant nodes of the BPD subtree. The root node implements the conventional network protocol and the custom network protocol.

摘要： One embodiment of the present disclosure sets forth a technique for resolving beaconing conflicts within a network. The technique includes detecting, by a first node in a network, a first scheduling conflict between a first time when a first beacon is to be transmitted from the first node and a first listening window when a second beacon is expected to be received from a second node in the network; determining, by the first node in response to detecting the first scheduling conflict and based on an expected transmission time for the second beacon and a position of the second node in the network, an alternate listening window during which to listen for a third beacon from the second node; and listening, by the first node, for the third beacon from the second node during the alternate listening window.

摘要： One embodiment of the present invention sets forth a technique for communicating within a network. The technique includes receiving, from a first node in the network and at a first receive time, a first periodic beacon that includes a first network time associated with the first node. The technique also includes determining a first transmission time of a first unicast message to the first node based on the first network time and a unicast interval between consecutive unicast listening times on the first node. The technique further includes transmitting the first unicast message to the first node at the first transmission time.

摘要： In various embodiments, a system within a wireless network comprises a set of battery-powered device (BPD) nodes within the wireless network, and a joining BPD node that identifies, in a subset of BPD nodes, a set of potential parent nodes, filters the set of BPD nodes based on network optimization criteria to identify a target parent node, and transmits a request message to establish a communications link with the target parent node as a child node, where the target parent node in the set of BPD nodes executes instructions to receive the request message from the joining BPD node, evaluate data associated with the joining BPD node with acceptance criteria, and upon determining that the joining BPD node meets the acceptance criteria, establish the communications link with the joining BPD node, where, upon the communications link being established, the joining BPD node is a child to the target parent node.

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： 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.
