1. A communication method based on a low mobility network, characterized in that:

  • the communication method comprises the following steps;

    the communication node judges the attribute of the communication frame sent this time;

    if the attribute of the communication frame sent this time is predictability, shortening the leader length of the communication frame sent this time;

    if the attribute of the communication frame sent this time is unpredictability, maintaining the leading length of the communication frame sent this time;

    the predictability of the communication frame includes the following;

    the object of the communication frame transmission and reception is determined or predictable, the time of the communication frame transmission is determined, the transmission signal strength of the communication frame transmitting end is determined, and the frequency offset between the transmitting and receiving nodes of the communication frame is determined;

    the unpredictability of the communication frame includes at least the following;

    the object of the communication frame transmission is not uniquely determined, or the timing of the communication frame is not predictable, or the signal strength of the communication frame transmission is uncertain;

    the communication node judges the attribute of the communication frame sent this time through the communication frame received last time;

    if the communication node needs the communication node to send a response frame after receiving the communication frame, judging the attribute of the sent communication frame as predictability;

    if the communication node continuously sends burst communication frames, judging that the attribute of the second frame and the subsequent communication frames in the plurality of continuous burst frames is predictability;

    if the communication node needs to send a communication frame with the same signal strength and the same receiving object after the communication frame is sent last time;

    the receiving node of the communication frame judges the attribute of the frame to be received based on the same judging method as the transmitting node of the communication frame;

    if the frame to be received belongs to predictability, a synchronization method for shortening the leading frame is adopted to receive the communication frame, otherwise, a synchronization method for normal leading frame is adopted to receive the communication frame;

    the communication method further includes;

    defining a plurality of communication frame formats with shortened preamble length corresponding to a plurality of communication frame formats with normal preamble length;

    the shortening of the preamble length of the communication frame sent this time means that the communication frame with the shortened preamble length is sent this time;

    the maintaining of the preamble length of the communication frame transmitted this time refers to the transmitting of the communication frame with a normal preamble length this time.
