摘　　要：论文研究了在有冲突的无线Mesh网络中,相对于存储转发机制,随机网络编码对文件共享所带来的下载时间的增益。仿真结果表明,当节点分别为移动和固定时,在盲转发(Blind-Forward)和选择性转发(Selective-Forward)节点协作方式下,随机网络编码均较大地降低了文件下载的时间。论文对仿真结果进行了性能分析。The paper studies the case that the download time gain brought by random network coding,compared to store-and-forward mechanism,on the file-sharing program in a collision-based wireless Mesh network.The simulation results show that, whenever the nodes in the network are fixed or not,compared to store-and-forward mechanism,random network coding can all reduce download time in both blind-forward and selective-forward node collaborative manners.The paper gives performance analysis for the simulation results in the end.
