  • Patent number: 11201821
    Abstract: A method and apparatus for dynamic medium switching in a hybrid network. A method for packet transmission by a combo device includes maintaining a wireless network confidence rating value that is indicative of packet transfer reliability of a wireless network accessed by the device. A wired network confidence rating value that is indicative of packet transfer reliability of a wired network accessed by the device is also maintained. One of the wireless network and the wired network to be used for initial transmission of the data packet is selected based on which of the wireless confidence rating value and the wired confidence rating value is indicative of a higher likelihood of the packet being successfully transmitted.

  • Patent number: 11197222
    Abstract: A network includes a mobile network node (MNN) that includes a mobile node communications manager (MNCM) to facilitate wireless communications to a plurality of stationary network nodes (SNNs) in a wireless network via a wireless network protocol. The MNCM utilizes a multicast address received over the wireless network. The multicast address is assigned to a predetermined network time slot to communicate uplink data from the MNN to the SNNs. The MNN receives downlink data via a separate predetermined network address and time slot assigned to a given SNN.

  • Publication number: 20210378002
    Abstract: A network includes a parent node and at least one child node configured to communicate with the parent node via a wireless network protocol. The parent node includes a broadcast coordinator to transmit a broadcast message from the parent node to the child node at predetermined time intervals according to the wireless network protocol. A scheduler generates a scheduling packet that is communicated in the broadcast message. The scheduling packet includes a data field to instruct each child node to activate and receive data communicated from the parent node in a prescribed time slot following the broadcast message that is defined by the scheduling packet.

  • Publication number: 20210314887
    Abstract: A network includes an intermediate node to communicate with a child node via a wireless network protocol. An intermediate node synchronizer in the intermediate node facilitates time synchronization with its parent node and with the child node. A child node synchronizer in the child node to facilitates time synchronization with the intermediate node. The intermediate node synchronizer exchanges synchronization data with the child node synchronizer to enable the child node to be time synchronized to the intermediate node before the intermediate node is synchronized to its parent node if the intermediate node has not synchronized to its parent node within a predetermined guard time period established for the child node.

  • Publication number: 20210152546
    Abstract: Authentication of a networked device with limited computational resources for secure communications over a network. Authentication of the device begins with the supplicant node transmitting a signed digital certificate with its authentication credentials to a proxy node. Upon verifying the certificate, the proxy node then authenticates the supplicant's credentials with an authentication server accessible over the network, acting as a proxy for the supplicant node. Typically, this verification includes decryption according to a public/private key scheme. Upon successful authentication, the authentication server creates a session key for the supplicant node and communicates it to the proxy node. The proxy node encrypts the session key with a symmetric key, and transmits the encrypted session key to the supplicant node which, after decryption, uses the session key for secure communications. In some embodiments, the authentication server encrypts the session key with the symmetric key.
