An apparatus, a method, and computer readable medium thereof for dividing a beacon interval are provided. The beacon interval is divided into a plurality of sub-beacon intervals in various sizes and each of the sub-beacon intervals is further divided into a predetermined number of time slots. Each of the sub-beacon intervals is similar to the beacon interval, and the difference between them is their time lengths. Therefore, more time slots in various sizes are provided. Consequently, nodes covered by the beacon interval can choose suitable time slots to transmit data to reduce waste of bandwidth. In addition, more time slots that are sub-contention free periods are provided, so transmitting data via time slots that are sub-contention access periods can be prevented. It means that collisions and data transmission can be reduced as well.
