Disclosed are a wireless peer to peer network system, a distributed peer discovering method for transmitting multimedia data in a wireless peer to peer network, and a method for responding to a request signal for requesting transmission of multimedia data in the wireless peer to peer network. An exemplary embodiment of the present invention provides a distributed peer discovering method for transmitting multimedia data in a wireless peer to peer network, the method including: transmitting a request signal including information on multimedia data to be requested by a first terminal, to neighboring terminals; when at least one second terminal having the requested multimedia data receives the request signal, determining a backoff duration in accordance with at least one of a signal to interference noise ratio of the request signal, an idle reproduction buffer capacity of the second terminal, and a remaining battery capacity of the second terminal and transmitting a response signal to the first terminal after standing by during the determined backoff duration; and transmitting a message for requesting transmission of the multimedia data to the second terminal transmitting the response signal first received by the first terminal.
