论文摘要
随着图像Internet（IoT）技术和机器类型通信的快速发展，工业生产和我们的日常生活中出现了各种新兴应用程序。其中，诸如工业感测和控制，远程手术以及自动驾驶等应用需要极低的延迟和非常小的抖动。确定性地提供信息已成为现代电线线和无线通信的最大挑战之一。在本文中，我们介绍了当前可用的电线确定性网络的评论，并讨论建立无线确定性网络的主要挑战。我们还讨论并提出了几种潜在的技术，使无线网络能够提供确定性的通信。通过详细阐述物理层的编码/调制方案，并在媒体访问控制（MAC）层管理频道访问/数据包安排，可以认为可以在不久的将来实现无线确定性通信。
With the rapid development of Internet-of-Things (IoT) technology and machine-type communications, various emerging applications appear in industrial productions and our daily lives. Among these, applications like industrial sensing and controlling, remote surgery, and automatic driving require an extremely low latency and a very small jitter. Delivering information deterministically has become one of the the biggest challenges for modern wire-line and wireless communications. In this paper, we present a review of currently available wire-line deterministic networks and discuss the main challenges to build wireless deterministic networks. We also discuss and propose several potential techniques enabling wireless networks to provide deterministic communications. By elaborating the coding/modulation schemes of the physical layer and managing the channel-access/packet-scheduling at the media access control (MAC) layer, it is believed that wireless deterministic communications can be realized in the near future.
