本文提出了一种适用于高相关帧错的移动无线信道的无线自组网节点合作自动重复请求（ARQ）方案。提出了一个基于两态马尔可夫过程的解析模型来描述所提出的重传方案的行为，并得到了它的吞吐量、平均延迟和延迟抖动。蒙特卡罗模拟的结果证明了所提方案的有效性，并验证了分析模型的准确性。结果表明，少量节点之间的协作可以通过减少重传试验的平均时间，在吞吐量、平均延迟和延迟抖动方面显著提高重传过程的性能。
In this paper, the authors propose a node-cooperative automatic repeat request (ARQ) scheme for wireless ad hoc networks, which is suitable for mobile wireless channels with high and correlated frame-error profile. An analytical model based on a two-state Markovian process is proposed to describe the behavior of the proposed retransmission scheme and to obtain its throughput, average delay, and delay jitter. The results of Monte Carlo simulations are included to demonstrate the efficacy of the proposed scheme and to verify the accuracy of the analytical models. Results show that a cooperation among a small number of nodes can significantly improve the performance of the retransmission process in terms of throughput, average delay, and delay jitter by reducing the average duration of retransmission trials.
