1. A system comprising:

  • a plurality of nodes; and

    a central node, wherein the plurality of nodes communicate with the central node using a Time Division Multiple Access (TDMA) communications network, wherein each of the plurality of nodes synchronizes an internal clock with an internal clock of the central node using an arrival time of a first packet received from the central node and a timestamp included in the first packet during entry into the TDMA communications network, and wherein each of the plurality of nodes subsequently maintains synchronization between the internal clock of the node and the internal clock of the central node using an arrival time for a subsequent packet and a time slot assigned for the subsequent packet in the TDMA communications network.
