Abstract: According to an exemplary embodiment of the present invention, a method for time synchronization of a first node in a peer aware communication (PAC) environment is provided. The first node obtains medium access control authority by performing contention with a second node neighboring the first node. The first node adds a time synchronization offset to the first beacon frame. In addition, the first node transmits the first beacon frame in a beacon period of a superframe when obtaining the media access control authority.

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.
