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.
