  • Publication number: 20240040466
    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.

  • Patent number: 11765749
    Abstract: A selected network element is arranged for distributed transmission resource allocation conflict reduction. The selected network element receives a transmission from one of a first other network element and a second other network element and identifies at least one transmission resource indicated by the received transmission as being reserved by the first other network element and the second other network element. The selected network element stores an indication of each of the at least one identified transmission resource. In response to reading the stored indications, the selected network element selects a different transmission resource that is different from the transmission resource indicated by the stored indications. The selected network element transmits a transmission from the selected network element using the selected different transmission resource.
