Abstract:
Although layered P2P streaming is perfectly adapted to heterogeneous network environments and heterogeneous user requirements, it suffers from bad delay performance like single-layer P2P streaming. In this paper, we analyze new characteristics of Pull-based P2P chunk scheduling problem caused by layered coding, and propose a Pull-based scheduling problem model aimed at enhancing the delay performance under the guarantee of video quality for layered P2P streaming. And then we put forward a heuristic chunk scheduling algorithm with aperiodic scheduling interval, where technique for order preference by similarity to ideal solution (TOPSIS) is utilized to solve several multiple-attribute decision making problems. Finally, we develop a new metric comprehensively evaluating video playback quality and delay performance, and simulations illustrate that our algorithm can greatly outperform the existing classical related work by a small increase in control overhead.
