基于Fourier矩阵的无线广播重传策略OA北大核心CSCDCSTPCD
Wireless broadcasting retransmission scheme based on Fourier matrix
针对随机网络编码重传的缺陷，将Fourier矩阵和随机网络编码相结合，提出一种半固定编码系数的广播重传方案FMWBR。利用广播源节点和接收节点双方已知的Fourier矩阵的行向量作为编/解码向量，保证接收节点接收到的重传包具有完全可解性。理论分析表明，FMWBR增强了无线传输的安全性、提高了网络的鲁棒性、减少了包头开销。仿真测试结果表明，FMWBR跟其他几种重传策略相比，有效地减少了平均传输次数，节省了带宽消耗，提高了网络吞吐量。
