Adaptive packet parity coding for loss-packet recovery

An adaptive packet parity coding is proposed for recovering the loss packets over packet loss network links. For every (n-1) packets of data, this coding scheme transmits an error-correcting packet that contains the XOR of the previous (n-1) packets of data. The block length n is adaptively controlled depending on packet loss characteristics in the decoding the block of n packets. The simulation shows that the adaptive packet parity coding scheme can satisfy a given block error rate requirement, even if the change of channel environment.
