Design of a Retransmission Strategy for Error Control in Data Communication Networks
Abstract
Several retransmission strategies with different degrees of flexibility for various applications in data Communication between two terminals are analyzed and compared with each other. A method for proving the correctness of a strategy is developed and used in each case. A new strategy for continuous transmission systems with variable block length (which is a rather general situation) is designed, using about one bit of error control data per block. It is an ordered retransmission scheme which assumes a constant round trip delay for the channel and takes advantage of this to specify block(s) in demand for retransmission. It has an advantage over other schemes designed earlier in the sense that it does not interpret an erased incoming block, as a block containing a repeat request, hence is more efficient. The strategy is then showed to be applicable to more specific cases such as constant block length and/or stop and wait transmission.
