A New Communication Protocol with Self Error Correction

Abstract

Communication in poor network environment is always a difficult problem, since troubles such as bit errors and packet loss may often occur. It is generally believed that it is impossible to transmit data both accurately and efficiently in this case. However, this paper provides a method to transmit data efficiently on the line where bit error may occur by utilizing Hamming code principle. If the sender adds a small amount of redundant data to the data to be sent, the receiver can self-correct them when an error is detected. This approach takes advantage of the value of packets with errors, which should have been discarded, reduce the number of re-transmissions and improve transmission efficiency. Based on this method, this paper designs a custom protocol which works in the data link layer and network layer. Finally, this paper verifies the protocol through mathematical simulation.
