摘要:

面对无线通信与多址边缘计算融合的趋势,研究了超五代网络中的计算卸载问题。为了解决MEC系统中的不确定性和有限资源共享所带来的技术挑战,我们将计算卸载问题表示为多代理马尔可夫决策过程,并提出了一个分布式学习框架。我们提出了一个案例研究的计算卸载资源编排展示潜力的在线分布式强化学习算法开发的框架下。实验结果表明,我们的学习算法优于基准资源编排算法。此外,我们概述了值得深入研究的研究方向,以尽量减少时间成本,这是一个主要的实际问题,防止建议的分布式学习框架的实施。

英文摘要:

Facing the trend of merging wireless communications and multi-access edge computing (MEC), this article studies computation offloading in the beyond fifth-generation networks. To address the technical challenges originating from the uncertainties and the sharing of limited resource in an MEC system, we formulate the computation offloading problem as a multi-agent Markov decision process, for which a distributed learning framework is proposed. We present a case study on resource orchestration in computation offloading to showcase the potentials of an online distributed reinforcement learning algorithm developed under the proposed framework. Experimental results demonstrate that our learning algorithm outperforms the benchmark resource orchestration algorithms. Furthermore, we outline the research directions worth in-depth investigation to minimize the time cost, which is one of the main practical issues that prevent the implementation of the proposed distributed learning framework.
