The invention discloses a mobile communication node networking control method based on a directional antenna. In the invention, a communication connection is established between the mobile nodes by using a bi-directional neighbor discovery method, and then the synchronous communication time is distributed to the mobile node and the neighbor node by using the TRC method, so as to maintain the communication connection between the mobile nodes; subsequently, during a period T2, the synchronous communication between the nodes is controlled by using a synchronous time control method so as to keep the communication connection between the nodes, and then the communication time is distributed to the mobile nodes by using the DTRC method; and finally, in a period T3, the communication between the nodes is controlled by using the bi-directional communication control method, and data exchange between the nodes is realized by using a data transmission control method, so as to realize communication between the nodes. The invention adopts a directional antenna to receive and send communication, and therefore, the communication distance between two parties is increased, the communication efficiency is improved, the conflict probability of the channels during the communication between the nodes is reduced, and the channel utilization rate and the communication efficiency are improved.
