Abstract:

In Mobile Network, a new data scheduling scheme named twodimension data scheduling scheme was propsoed to be used in wireless mobile P2P(PeertoPeer) streaming to address the scheduling issue in layered streaming. In the scheme, each data in the streaming was marked with twodimensional coordinates (blcok coordinate and layer coordinate), and the scheduling order of the data is determined by its twodimensional coordinates. The main contribution of our scheme comes in threefold:  it can assure the fluency of vedios playback on the mobile terminal;  making best use of the wireless bandwidth with minishing the useless packet ratio; achieving a low subscription ratio which brings the quality of the streamings stability.
