1. A method comprising:

  • receiving, from a destination node in a network, a broadcast that includes a current position and a bearing of the destination node, wherein the broadcast is made at a frequency that is directly proportional to a velocity of the destination node;

    calculating an estimated propagation time for a data packet to arrive at the destination node, wherein the estimated propagation time is based at least in part on a prior transmission from the destination node; and

    calculating an estimated future location of the destination node based at least in part on the broadcast from the destination node and at least in part on the estimated propagation time; and

    routing the data packet to an intermediate node based at least in part on the estimated future location of the destination node.
