| 摘 要： | 在无线网络广播传输中，为了提升效率提出改进的基于冗余避免的网络编码广播重传算法（INCBRRA）。对接收状态矩阵进行重排列后，再主动避免重传不可解码的编码组合，从而优先编码有助于接收节点解码的丢失数据包组合。分析结果表明，INCBRRA算法相比于现有算法能有效减少重传次数，提升了传输效率。

| Abstract: | For the purpose of improving the transmission efficiency of the network coding broadcasting retransmission method, thus reducing the retransmission times, an improved network coding broadcasting retransmission algorithms based on redundancy avoiding(INCBRRA) is proposed. After rearrange the receive matrix, it voluntarily avoids redundant transmission of the combination which can not decoded by the receiving nodes, and preferentially codes the lost packets which are conducive to decoding. The analysis results shows that compared to existing algorithms, INCBRRA can reduce the number of retransmission times and improve the transmission efficiency. |
