PURPOSE: A message transmission cycle determining method is provided to improve the accuracy of neighbor node search by exchanging a hello message through a hello message transmission cycle determining method. CONSTITUTION: A message transmission cycle determining device calculates a cross point between a first transmission range and a second transmission range(S201). The message transmission cycle determining device calculates an angle according to a moving speed of a first node and a distance between the first node and a second node using the calculated cross point(S202). The message transmission cycle determining device calculates probability related to the transmission range of the second node using the calculated angle(S203). The message transmission cycle determining device calculates a transmission cycle which the first node transmits the message to the second node(S204).
