Application of random relaying of partitioned MDS codeword block to persistent relay CSMA over random error channels

We propose an incorporation of random relaying of MDS codeword blocks (RP-MDS), which has been proposed for multi-hop cooperative relay networks, to persistent relay CSMA (PRCSMA) over noisy channels. The proposed protocol elaborately employs the powerful error-correcting capability of MDS codes into cooperative communication systems and introduces the incremental redundancy concept to PRCSMA. A destination node can reinforce an error-correcting capability when it receives a new frame. The performance of the proposed protocol is compared to PRCSMA by means of computer simulation. Numerical results indicate that the proposed protocol can significantly reduce the duration of the cooperation phase and provide robust and stable performance against channel impairments.
