Abstract: In layered design, the link level guarantees reliable transmission.This paper proposes a design of retransmission mechanism which has low-cost and high-performance at the link level and implements it with some mode. And simulates complicated acknowledgement schema and enhanced acknowledgement schema and gives a performance evaluation with simulating results.
