摘　　要：分析了合作多路径传输中的复数域网络编码问题.提出了在WSN转发节点中使用复数域网络编码和合作多路径机制（CFNC-CM）进行数据分组的传输和转接机制,复数域网络编码的数据分组由中继转接节点进行编码后再转发到多路径进行数据分组的传输.通过仿真实验对2种典型的路由协议在数据分组开销、数据分组传输率和网络生存期等测量参数方面进行了性能分析和比较.仿真实验结果表明：CFNC-CM机制能较好地用于WSN网络中,相对传统机制,CFNC-CM机制能提高5%~15%的性能.The performance analysis and the complex field network coding（CFNC）scheme in cooperative multipath were presented in this paper.Complex field network coding and cooperative multipath（CFNC-CM）relaying node which operates over WSN was proposed to use.Encoding packet was generated by a relay node.Simulation experiment of two kinds of typical routing protocol was analyzed and compared in packet overhead,packet delivery rate,and network lifetime such measurement parameters and so on.The simulation results show that CFNC-CM mechanism can be better used in WSN network,and using distributed detection with CFNC-CM can obtain up to a 5%~15%improvement rather than employing the conventional method in literature.
