摘　　要：网络编码可以提高无线Mesh网络的吞吐量,但是网络编码在无线Mesh网络中实际应用获得最大网络利用率是需要解决的问题。提出一种多路径策略,能够通过将网络编码和TCP进行最大化融合提高网络的利用率。网络编码被加入到现有的网络系统,通过解决速率控制问题和分组调度问题,调整源节点的数据编码分块,降低数据包重传的次数,提高网络的吞吐量。Network coding can increase the throughput of wireless Mesh networks, but to obtain the maximum utilization of the network in the practical application of network coding in wireless Mesh networks is the problem which needs to be solved. A multi-path routing strategy is proposed in this paper. It can improve network utilization by maximization fusion of the network coding and TCP. As the network coding was added to the existing network system, the number of data packet retransmission was reduced and the network throughput was increased by realizing rate control and packet scheduling, and adjustment data coding block of the source node block.
