We have proposed two methods of 1 bit error tolerance of the protocol for reticent sender cooperated with aggressively speaking receiver which is effective in the asymmetric channel. One is the method by error detection and resend, the other is by error correction code. Former can reduce the number of bits sent from user, but causes large delay. On the other hand, later can reduce its delay, but increases the number of bits.
We show trade-off relation between two parameter, the number of bits and delay, by theoretical analysis.
