Abstract

Modern mobile devices have become an important part of our daily life but the performance of multimedia applications on mobile devices still suffers from the constrained energy supply and shared cellular link bandwidth. In this work, we design a cooperative energy-efficient P2P streaming system to achieve better Quality-of-Experience for a mobile user. First, we formulate and analyze the problem of Maximizing the Lifetime for a mobile P2p Streaming system (MLPS). Then, our distributed bit rate-aware entrust algorithm, jointly considering characteristics of mobile devices and steaming services, is proposed. The simulation results show our scheme can improve the system lifetime by 8 times, and provide more than 2 times throughput than the conventional 3G system does.
