摘要:

近年来,从理论和仿真两个角度,已经进行了大量的研究来探索网络编码在不同场景中的益处。本文利用排队论提出了多跳无线网状网中双向单播流的分析框架,并研究了流间网络编码的吞吐量。我们分析确定的性能指标,如成功传输的概率方面的冲突概率,反馈机制和重传。关于编码过程,我们的模型使用了一个多类排队网络,其中编码的数据包与本地数据包分离,并且具有比本地数据包更高的非抢占式优先级,并且两个队列都处于稳态。最后,我们使用模拟来验证我们的分析模型的准确性。

英文摘要:

In recent years, a significant amount of research has been conducted to explore the benefits of network coding in different scenarios, from both theoretical and simulation perspectives. In this paper, we utilize queueing theory to propose an analytical framework for bidirectional unicast flows in multi-hop wireless mesh networks, and study throughput of inter-flow network coding. We analytically determine performance metrics such as the probability of successful transmission in terms of collision probability, and feedback mechanism and retransmission. Regarding the coding process, our model uses a multi-class queueing network where coded packets are separated from native packets and have a non-preemptive higher priority over native packets, and both queues are in a stable state. Finally, we use simulations to verify the accuracy of our analytical model.
