Comprehensive-factors-based scheduling algorithm for P2P media streaming

Abstract

A comprehensive-factors-based (CFB) scheduling algorithm is proposed for Peer-to-Peer media streaming. In CFB, considering the number of chunks' suppliers and urgency, a priority is defined for each data chunk and the neighbours' bandwidth is effectively evaluated. A peer requests chunks from neighbors according to priorities as well as bandwidth. Simulation results show that the proposed CFB scheduling algorithm for Peer-to-Peer media streaming outperforms conventional scheduling algorithms in peer average throughput, continuity index and start delay.
