Feedback adjustment scheme for multiple network coding in mobile P2P

采用网络编码的数据分发方案,虽然可降低移动P2P的能量消耗,但在动态网络环境下,其数据分发效率受到网络拓扑动态变化的限制。为提高移动对等网数据分发效率,降低能量消耗,对移动对等网环境下的网络编码进行研究。提出了多次网络编码,并设计了移动P2P中多次网络编码反馈调节数据传输方案。方案增加了编码节点的编码次数,加大了下游节点的数据接收量,可以缩短动态网络环境中数据分发时间。实验结果与理论分析一致,实验结果表明方案可有效地提高了数据分发效率。

The data distribution scheme utilizing network coding can reduce the energy consumption of mobile peer-to-peer （mobile P2P）.However, the efficiency of data distribution is limited by the dynamic variation of the net-work topology in the dynamic network environment.To improve the data distribution efficiency of mobile peer-to-peer network and reduce the energy consumption, network coding is studied in mobile P2P.Multiple network cod-ing is proposed and multiple network coding feedback adjustment data transmission scheme is designed in the mo-bile P2P.The scheme also increases the coding times of the coding node and improves the amount of data reception of the downstream nodes.It was also shown to possibly shorten the time of data distribution in the dynamic network environment.Experimental results are consistent with theoretical analysis.The experimental results showed that the scheme can effectively improve the efficiency of data distribution.
