针对无线信道中高误码率限制传输性能,固定前向纠错(FEC)又不能适应无线网络中误码率多变和链路差异的环境等问题,通过利用主动网的网络可编程接口在Ad hoc网络中动态地实现了一种跳到跳的自适应前向纠错策略,并采用仿真实验进行性能分析,结果表明:能对上述原因造成的丢包起到很好的改善作用。This paper proposes an active network by using adaptive Forward Error Correction (FEC) strategy which is hop-to-hop for improving transmission performance in Ad hoc networks. Fixed FEC can’t perform well while wireless link is characterized by high and variable BER (Bit Error Rate). The performance of this strategy is analyzed via simulation experiments by using the Gilbert model as a wireless error model. Finally we demonstrate our method achieves better performance than fixed FEC.
