With the increase of data transfer rates beyond 100Mbit/s over the infrared links, a robust automatic repeat request (ARQ) scheme is necessary to cope with the high speed environment. At high data rate, the Go-Back-N (GBN) ARQ scheme requires window and frame size adaptation to the corresponding optimum values for the correspondent Bit Error Rate (BER). But adaptive approaches always add a significant amount of complexity to the system. This paper presents a non adaptive Block Based Window Retransmission (BBWR) ARQ scheme that operates with a fixed size receiver buffer and achieves a significant improvement in the throughput efficiency over a wide range of BER at 100Mbit/s infrared links. Simulation results are presented which also reveal the effect of link layer parameters, such as window and frame data length, and physical layer parameters, such as minimum turn around time on the performance of the proposed scheme.
