Abstract: A method and apparatus having advantages of resolving a phenomenon in which traffic is concentrated on an AP of a wireless network and preventing traffic collision to enhance network efficiency are provided. Thousands or more of nodes included in a wireless network can be connected to the wireless network through a plurality of distributed association nodes, rather than through a single AP, and thus, concentration can be resolved and the wireless network can be effectively operated. Also, by performing distributed association on the basis of a single hop, implementation complexity can be lowered.

Abstract: A synchronization method performed by a first communication node may include: receiving, from a second communication node of the communication system, a first synchronization information signal including information on a first synchronization reference time and information on a first offset; identifying information on a first time at which the first synchronization information signal is transmitted and information on a target synchronization time configured by the second communication node, based on the information included in the first synchronization information signal; setting a synchronization timer based on the information on the first offset; and when the synchronization timer expires, determining that time synchronization with the second communication node is acquired.
