Abstract
In this paper, we propose an improved selective-repeat automatic repeat request (ARQ) scheme which operates with a finite receiver buffer. The throughput performance of the proposed ARQ scheme is examined and compared with the throughput of the IrDA adopted go-back-N ARQ scheme over half-duplex infrared links. Simulation results show that it significantly outperforms the existing go-back-N ARQ scheme, particularly for links with high bit error rate. We also explore that without adapting window size at high bit error rate, the proposed scheme provides a significant improvement in the throughput over a range of bit error rates including high bit error rate. The proposed ARQ scheme is a good compromise between the go-back-N ARQ and the ideal selective repeat ARQ in throughput performance and receiver buffer size. Therefore, it would be applied on IrDA links for achieving high throughput at high error rate.
