Applying data carousel to improve search efficiency in P2P system

In recent years, advanced data broadcasting services, which provide viewers with multimedia data on digital television, have drawn growing interest. At the same time, there is file-sharing peer-to-peer service on digital television field. However, few studies pay attention to their convergence that is data broadcasting can help peer-to-peer service. This paper studies file-sharing peer-to-peer application among set-top boxes in bidirectional HFC networks. The study proposes the new architecture that using data carousel completes search work in peer-to-peer system. Finally, the experiment demonstrates advantages of the proposed strategy in hybrid peer-to-peer system.
