When the same content is simultaneously downloaded by several terminals with unicast in a wireless LAN, the bandwidth must be divided among the terminals and download speed is reduced. With using broadcast nature of wireless media, we propose an efficient method that can achieve reliable content distribution by using overheard TCP flows of a specific content going to other terminals in a wireless LAN. In the proposed method a content is divided into pieces and the server distributes them according to the download status of the receivers in application level. To accelerate downloading, we propose a method for selecting the piece and the terminal for transmission taking the effect of network coding for efficient overhearing. We developed a testbed and confirmed that the proposed scheduling accelerates the download speed even where the communication speed of each terminal is different.
