On the performance of ARQ protocols in infrared networks

Abstract

In this paper we address the retransmission techniques in the infrared link access protocols in the infrared wireless networks. We present the performance of the Go‐Back‐N and Selective–Reject automatic repeat request protocols in the infrared link access control layer. The effects of the parameters, such as the window size, packet error rate and processor speed, are discussed. We investigate which link parameter is dominant in the performance under different link conditions. The optimal packet sizes for the ARQ protocols are also addressed. It is concluded that processing time affects the performance more than channel capacity after accomplishing a certain bit error rate. We also introduce the use of packet‐level acknowledgements in the infrared medium access control layer, which is a way of using Stop‐and‐Wait ARQ in the infrared media access control layer as well as the Go‐Back‐N ARQ in the infrared link control layer. The performance of the system is given in the presence of adaptive data rate mechanism over L‐PPM wireless links. Copyright © 2000 John Wiley & Sons, Ltd.

“…The combination of ARQ and PPM was first presented in Refs. [18,19], which have investigated the performance of infrared communication systems using repetition-rate coding and ARQ schemes over PPM wireless links throughout indoor environments. The scheme has the advantage that there is no need to use other error detecting codes in the data packet, and its drawback is a low throughput efficiency because each PPM symbol is repeated; in Ref.…”

“…Furthermore, in Refs. [18][19][20][21], the whole packet must be retransmitted when the packet's parity check fails. In that case, the successfully decoded portion of the packet is still retransmitted, and it brings about the waste of communication resources.…”

On Coding for Delay—Network Coding for Time-Division Duplexing

“…A TDD channel is usually called half duplex, but we prefer the term TDD to emphasize that the channel is not assigned half of the time to the receiver and half to the transmitter or in any predetermined fashion. Important applications can be found in infrared devices (IrDA) [16], [17], underwater acoustic communications [18], and in very high latency conditions (e.g., satellite and deep space communications) [19]- [21].…”

“…The mean time to complete the transmission and get an ACK is (14) where is the time to complete transmission of packets. The mean energy to complete the transmission and get an ACK is (15) 5) Go-Back-N ARQ for TDD (GBN): This is an ARQ scheme developed for a TDD duplex channel in [16]. Each transmission contains data packets sent back-to-back, where is the window size.…”
