Packet Reversed Packet Combining Scheme: A Thorough Analysis

Packet Reversed Packet Combining (PRPC) Scheme corrects error if occurs at same bit location. A Modified Packet Combining (MPC) Scheme corrects double or higher bit errors. Some previous studies on three schemes namely PRPC, MPC and MPC with PRPC found that they offer higher throughput over basic stop and wait ARQ protocol. We find that in practical ranges of packet size, window size and bit error rate, the schemes offer higher throughput than that of basic GBN.
