摘要 该文研究了海量无线终端场景中的高效数据广播问题。提出了一种有限反馈随机网络编码自动重传请求(Finite feedback Random Network coding Automatic Repeat re Quest,FRNARQ)方案。通过设计最优度反馈机制,有效降低海量无线终端数据广播系统的反馈负载,并利用有限随机网络编码进一步降低数据包平均传输次数。数值仿真表明,与部分反馈选择性自动重传请求方案(Partial feedback Selective ARQ,PSARQ)和网络编码自动重传请求方案(Network coding ARQ,NARQ)相比,FRNARQ能够在保证数据包平均传输次数较小的前提下,有效降低系统的反馈负载,提高数据广播效率。
