近年来，在物理层引入网络编码以增加无线网状网络（WMN）的网络容量。在本文中，支持可靠的数据包中继在WMN采用网络编码，我们提出了一个有效的重传方案。所提出的方案是有效的，因为它利用网络编码的数据包报头的属性，而不是使用传统的方案的基础上传输的确认（ACK/NAK）数据包的分析结果所示。所提出的方案的好处进一步验证了在一维（1D）MIMO双向中继网络采用网络编码。数值结果表明，我们所提出的方案可以显着提高端到端的分组投递率在有损无线链路的存在。
In recent years, network coding has been introduced at physical layer to increase network capacity of wireless mesh networks (WMN). In this paper, to support reliable packet relaying in WMN employing network coding, we propose an efficient retransmission scheme. The proposed scheme is efficient since it exploits the property of network coded packet header instead of using conventional schemes based on transmission of acknowledgement (ACK/NAK) packets as　shown by analytic results. Benefit of the proposed scheme is furthermore verified in a one dimensional (1D) MIMO two-way relay network　employing network coding. Numerical result shows that our proposed　scheme can ｓignificantly improve end-to-end packet delivery ratio in　the presence of lossy wireless links.
