  • Patent number: 12677126
    Abstract: An integrated circuit for use in a wireless management system with a primary node and secondary nodes includes: a wireless transceiver; and a wireless management controller included with or coupled to the wireless transceiver. The wireless management controller is configured to: identify a first secondary node of the secondary nodes in communication with the primary node; identify a second secondary node of the secondary nodes not in communication with the primary node; and enable the first secondary node to operate as a proxy node that repeats downlink messages to or uplink messages from the second secondary node.

  • Publication number: 20260149483
    Abstract: Systems and methods for setting a carrier-sensing mechanism in a PLC node are disclosed. In a PLC standard, coexistence is achieved by having the nodes detect a common preamble and backing off by a Coexistence InterFrame Space (cEIFS) time period to help the node to avoid interfering with the other technologies. In one embodiment, a PHY primitive is sent from the PHY to the MAC know that there has been a preamble detection. A two-level indication may be used—one indication after receiving the preamble and other indication after decoding the entire frame. The MAC sets the carrier-sensing mechanism based on the preamble detection.

  • Publication number: 20250242718
    Abstract: In examples, a vehicular battery management system (BMS) comprises a set of battery cells and a secondary network node coupled to the set of battery cells. The secondary network node is configured to measure a parameter in the set of battery cells and generate a packet containing the parameter. The packet indicates a number of super frame slots that have elapsed from a start time of a super frame to the generation of the packet. The secondary network node is configured to wirelessly transmit the packet within the super frame to a primary network node. The primary network node is configured to wirelessly receive the packet and to determine a time at which the secondary network node generated the packet based on the indication, a time duration of each slot in the super frame, and the start time of the super frame.

  • Publication number: 20250211492
    Abstract: An algorithm for the promotion of terminal nodes to switch nodes in a PLC network reduces overall network overhead and collisions, while ensuring the appropriate selection of a switch node and minimizing the number of levels in a PLC network. It also ensures that the terminal nodes with appropriate signal-to-noise ratios (SNRs) are promoted. It is desirable to have a network with fewer levels. The disclosed approach favors the nodes that are closer to the DC to promote them as switch nodes. This is achieved by waiting for a smaller number of PNPDUs for a node that is closer to the DC in comparison to a node that is farther away from the DC.

  • Publication number: 20250168143
    Abstract: A network includes at least two nodes that employ a routing protocol to communicate across a network. One of the nodes is a parent node and another of the nodes is a child node of the parent node. An address generator assigns a unique network address to the child node by appending an address value of a number of bits to a parent address of the parent node to create the unique network address for the child node.

  • Publication number: 20250168159
    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.

  • Publication number: 20250106914
    Abstract: An emulated wireless access point (AP) at a first PMC device (PMC1) establishes a first tunneled direct link setup (TDLS) session between a first station module (STA1) incorporated into the PMC1 and a second station module (STA2) incorporated into a second PMC device (PMC2). Following establishment of the TDLS session, the wireless AP is allowed to sleep; and most infrastructure management duties are handled by the STA1 during the session. PMC device battery charge may be conserved as a result. The emulated wireless AP may also establish a second TDLS link to a third station module (STA3) incorporated into a third PMC device (PMC3). The STA1 may then bridge data traffic flow between the STA2 and the STA3. Such bridging operation may enable communication between two PMC devices otherwise unable to decode data received from the other.
