1. A method for optimizing data transferred between vehicles, said method comprising:

  • determining if there are missed packets in a sequence of status messages transmitted between two vehicles;

    determining if a number of successful packet transfers is greater than or equal to a successful packets threshold and if a received signal strength indication is increasing, if there are no missed packets in the sequence of messages;

    determining if a number of missed packet transfers is greater than or equal to a missed packets threshold and if a received signal strength indication is decreasing, if there are missed packets in the sequence of messages;

    increasing a length of a message packet by a predetermined packet increase amount if the number of successful packet transfers is greater than or equal to the successful packets threshold and if the received signal strength indication is increasing;

    decreasing the length of the message packet by a predetermined packet decrease amount if the number of missed packet transfers is greater than or equal to the successful packets threshold and if the received signal strength indication is decreasing; and

    resetting the number of missed packet transfers and the number of successful packet transfers if packet settings have changed.
