Adaptive FEC Based Active Network in Ad hoc Network

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.
