  • Patent number: 11848793
    Abstract: Techniques and devices for expressing multicast groups using Weave traits are described for generating a multicast address in which a wireless network device receives an application group identifier and hashes the application group identifier to generate a group identifier. The wireless network device concatenates a global identifier and a Weave fabric identifier, inserts the concatenated global identifier and the Weave fabric identifier into a network prefix field of a destination address and inserts the group identifier into a group identifier field of the destination address. The wireless network device sets the value of a plen field of the destination address to a value that indicates a length of the Weave fabric identifier and inserts the destination address into an Internet Protocol version 6 data packet.

  • Publication number: 20230262578
    Abstract: Techniques and devices for multicast address subscriptions in a wireless mesh network are described in which a mesh network device generates a Multicast Listener Discovery, MLD, Report message including a multicast address. The mesh network device sends the generated MLD Report message to a network interface and a Wireless Personal Area Network, WPAN, Tun interface intercepts the MLD Report message. The mesh network device parses the intercepted MLD Report message to extract the multicast address, translates the intercepted MLD Report message into a mesh network Application Programming Interface, API, function call to join the multicast address, and invokes the API function call on a mesh network interface to transmit a multicast join request message over the mesh network.

  • Patent number: 7881206
    Abstract: Method and apparatus for optimizing mesh routing for stability and system lifetime maximization in networks, for example in wireless networks. A routing module may be instantiated in nodes on the network. The routing module may implement a link quality and node health aware routing protocol on the network that considers a combination of link quality and node health/residual lifetime metrics in the calculation of the desirability of nodes and links between nodes as parts of an overall route. A route selection metric for each route may be determined from routing cost metrics for the nodes on the route and the number of hops on the route. A node may then select a best route according to the determined route selection metrics for the routes.
