In order to maximize the throughput in a new ARQ strategy proposed by Weldon, a number of parameters need to be selected optimally. An efficient method for choosing these parameters is obtained by exploiting the form of a simplified expression for the throughput.

Proceedings 2001 Pacific Rim International Symposium on Dependable Computing, 2002
The errors in optical communication are of the asymmetric type. Using the Z-channel model, the Bose-Lin asymmetric error detecting codes are analyzed as part of a feedback communication system. The probabilities of detectable and undetectable errors are derived from the code construction using certain properties of the information and check sequences ...

The performance of stop-and-wait, go-back-N, and selective-repeat ARQ protocols is examined for a multichannel system. The channels can either operate independently or jointly. For each protocol, the results obtained include throughput efficiency and delay. The results are also validated by computer simulations.

Although the wireless communication systems offer limitless possibilities of service utilization, these systems are not error free. Variable error rate of these systems is the main reason of being concerned with error control techniques. Selection of suitable error control techniques is very important and depends on performance.

ARQ performance in SNA networks
Proceedings of the May 19-22, 1980, national computer conference on - AFIPS '80, 1980In order to examine various data link control (DLC) procedures, one must first have a basic understanding of the overall network. The network depicted will be one implementing the IBM Systems Network Architecture (SNA). The fundamental communication system within SNA is referred to as the Transmission Subsystem.

On Revealing the ARQ Mechanism of MSTV
2011 IEEE International Conference on Communications (ICC), 2011Ensuring a high customer satisfaction by monitoring Quality of Experience (QoE) aspects has become common practice for service providers. Such monitoring solutions, together with underlying QoE models, are mostly limited to measures captured in the core or access network and may thus neglect the QoE impact of recovery mechanisms deployed at client-side,

2008 IEEE Wireless Communications and Networking Conference, 2008
In this paper, multiuser ARQ is extended to multicasting. The core idea is that the sender, based on feedback from users regarding successfully received transmissions, adapts code weights for data packet linear combinations that are then sent. Each user exploits its previously received information in decoding the linearly combined packets. Specifically,

Wireless scheduling with hybrid ARQ
IEEE Transactions on Wireless Communications, 2005A model for downlink wireless scheduling is studied, which takes into account both user-channel conditions and retransmissions with packet combining hybrid [automatic repeat request (ARQ)]. Quality-of-service (QoS) requirements for each user are represented by a cost function, which is an increasing function of queue length.

Cooperative hybrid ARQ networks
2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014In this work, the performance contribution of a relay node which cooperates to a source node during the transmission of data packets from source node to destination node is investigated. The effect of diversity gain to the performance of a network consists of correlated flat-faded Rayleigh channels.

Delay Performance Analyses for GBN-ARQ and SR-ARQ Protocols
2007 International Conference on Wireless Communications, Networking and Mobile Computing, 2007Automatic repeat request (ARQ) is an important error-control protocol in wireless communication. In this paper, by analyzing the transmission mechanism of ARQ protocols and the existent literatures, the queuing models for both GBN-ARQ protocol and SR-ARQ protocol are established sententiously based on Equivalent Service delay, in which the packet ...
