Abstract: A dynamic routing method of a network device in an ad-hoc network is provided. The method includes (a) collecting a factor comprising at least one of the number of neighboring network devices, a moving speed and an amount of data traffic; (b) setting a routing information transmission mode based on a value of the collected factor; and (c) processing at least one of transmission and non-transmission of routing information according to the set routing information transmission mode, wherein in the step (b), when setting the routing information transmission mode, if the value of the factor is less than a preset threshold value, the routing information transmission mode is set to an active mode, and if the value of the factor exceeds the threshold, the routing information transmission mode is set to an inactive mode.
