  • Selective relay of network protocol data units in a wireless mesh network
    Patent number: 11617104
    Abstract: A node in a wireless mesh network determines that a threshold level of duplicate network protocol data units (PDUs) are received. Further, the node receives one or more network PDUs comprising respective segments of transport data in a transport PDU. The node relays a subset of the received one or more network PDUs comprising respective segments to one or more neighboring nodes. The subset is relayed based on determination that the node has received a threshold level of duplicate network PDUs.
    Type: Grant

  • Unreachable node recovery in wireless mesh networks
    Patent number: 11076441
    Abstract: A mesh network system is provided that enables a parent node to regain communication with a child node that is unresponsive due to bad link conditions on the currently used communication channel. The parent and the unresponsive child node are configured to respond to unreachability conditions by having synchronized transmit and reception scans for signals on each available channel. Once a determination has been made that an alternate channel is available that allows communication, embodiments further provide a mechanism for determining whether to trigger a network-wide channel switch, if, for example, the node is critical to an application supported by the network.
