摘要:
本信研究了ETSI TS 102 687 V1.2.1规范中定义的自适应去中心化拥塞控制(DCC)算法。我们深入探讨了该算法使用的参数,并分析了这些参数对其性能的影响。我们展示了该算法如何实现良好的平均介质利用率并防止拥塞,但也揭示了所选参数如何导致收敛速度缓慢及瞬态情况下长期的公平性问题。最后,我们提出对该算法的修改,使收敛速度和公平性得到显著改善。
英文摘要:
This letter studies the adaptive Decentralized Congestion Control (DCC) algorithm defined in the ETSI TS 102 687 V1.2.1 specification. We provide insights on the parameters used in the algorithm and explore the impact of those parameters on its performance. We show how the algorithm achieves good average medium utilization while protecting against congestion, but we also show how the chosen parameters can result in slow speed of convergence and long periods of unfairness in transitory situations. Finally, we propose a modification to the algorithm which results in significant improvements in speed of convergence and fairness.
