Abstract: Techniques for determining network reliability using message success rates include a first node in a mesh network computing a transmitted message success rate associated with a connection from the first node to a second node, wherein the second node is a neighbor node to the first node; computing, based on a first accumulated transmitted message success rate and the transmitted message success rate, a second accumulated transmitted message success rate for a route from the first node to a target destination using the second node, wherein the first accumulated transmitted message success rate is received from the second node and is associated with intermediary connections between the second node and the target destination; selecting, based on the second accumulated transmitted message success rate, the second node from a plurality of neighbor nodes; and transmitting a message to the target destination via the second node.

Abstract: One embodiment of the present invention sets forth a technique for evaluating connections between nodes in a mesh network. The technique includes identifying a plurality of potential parent nodes for a first node included in the mesh network; computing, for each potential parent node, one or more accumulated message success rates associated with transmitting messages from the first node to a target destination within the mesh network via the potential parent node and with receiving messages from the target destination via the potential parent node; and selecting, from the plurality of potential parent nodes and based on the accumulated message success rates, a parent node for the first node.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Techniques for network reliability include, in response to determining, at a first node in a mesh network and based on a first combined accumulated message success rate, that a search for a different parent node should be performed: performing one or more communication operations to discover a plurality of nearby nodes; computing respective second combined accumulated message success rates associated with respective nodes of the plurality of nearby nodes; and based on the respective second combined accumulated message success rates, selecting a new parent node from the plurality of nearby nodes or maintaining an established parent node. The first combined accumulated message success rate is based on an accumulated uplink message success rate, a first offset value associated with the accumulated uplink message success rate, an accumulated downlink message success rate, and a second offset value associated with the accumulated downlink message success rate.

Abstract: Techniques for managing message transmission using forward error correction include determining, by a communication application executing on a first node device based on one or more consecutive attempts to transmit messages to a second node device without using forward error correction (FEC) being unsuccessful, to use FEC to transmit messages to the second node device; and transmitting, by the communication application in response to determining to use FEC to transmit messages to the second node device, a first message to the second node device using FEC.

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: A network system includes a main network implementing a conventional network protocol and a subtree of battery-powered nodes implementing a custom network protocol. The main network and the subtree are managed according to different subtree parameters. When a root node receives a request by a battery-powered node to join the subtree, the root node determines whether to allow the battery-powered node to join based on the subtree parameters for the subtree before sending a response to the battery-powered node.

Abstract: A network system implements a network protocol for devices and nodes withing a wireless network. A first node within a subtree of nodes in the wireless network performs a method including receiving a discovery request from a second node included in the wireless network, determining that an address associated with the second node is not included in a first address list that includes addresses of nodes along a node path between the first node and a root node of the subtree of nodes, and sending, in response to the determining, a response to the discovery request.
