TL;DR

This paper proposes an isochronous data transmission strategy for delay-tolerant applications that maintains near-capacity throughput by optimizing retransmission block size based on a robustness criterion.

Contribution

It introduces a novel retransmission strategy that ensures constant throughput close to channel capacity under delay tolerance constraints.

Findings

Achieves near-capacity throughput in delay-tolerant scenarios

Optimizes retransmission block size using a robustness criterion

Maintains constant throughput until robustness criterion fails

Abstract

The existing ARQ schemes (including a hybrid ARQ) have a throughput depending on packet error probability. In this paper we describe a strategy for delay tolerant applications which provide a constant throughput until the algorithm robustness criterion is not failed. The algorithm robustness criterion is applied to find the optimum size of the retransmission block in the assumption of the small changes of coding rate within the rate compatible codes family.
