摘　　要：移动对等网底层网络具有明显异构性,单速率组播方案不能充分利用网络资源,高性能的节点存在资源使用不公平的问题。对多速率组播与代间混合编码进行扩展,提出了一种基代间混合的多速率网络编码方法,并设计了适合移动对等网的速率分配方案。实验结果表明,代间混合的多速率网络编码方法能够提高网络资源使用公平性,增大网络的最大流比率。There is obvious heterogeneity in the underlying network of mobile P2P network, single rate multicast scheme can not make full use of network resources, it is unfair to high-performance node when they are in the same multicast rate. This paper proposed a multi- rate network coding with multigeneration mixing (MNC-MGM) and brought a rate allocation scheme used in mobile P2P network after expanding multi-rate multicast technology and network coding with multi-generation mixing. The results show that MNC-MGM can improve the fairness of network resources, and increase the network max-low rate.
