Data Scheduling Algorithm in Mobile P2P Streaming

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.
