Abstract: In response to the issue of mobile terminal heterogeneity in the existing Peer-to-Peer (P2P) data sharing network, an energy-aware P2P data sharing mechanism in heterogeneous mobile terminal named EADS was proposed, which enabled terminals to determine the types of end-user devices with introducing an energy-aware module to predict residual energy of these end-user devices. On this basis, the mechanism adjusted data sharing strategy dynamically in accordance with the changes of network environment. The simulation results demonstrate that EADS achieves significant performance improvement, in terms of energy utilization efficiency, balance load, as well as data sharing time, thus enhancing the success rate of data distribution. On the premise of maintaining high availability of files, average energy consumption has been reduced up to 15%.

摘要: 针对现有P2P数据共享网络中存在的移动终端异构性这一问题,提出一种异构移动终端能量感知的P2P数据共享机制。该机制在判断移动终端类型的同时引入能量感知模块,用于预测终端的剩余能量,在此基础上,根据网络环境的变化动态地调整数据的共享策略。仿真实验表明,该机制能够有效提高移动终端的能量利用率,平衡终端的负载,延长数据共享时间,从而提高数据分发成功率。在保持文件高可用性的前提下,平均减少15%的终端能耗。
