论文摘要
在这本两部分的论文中，我们为工业互联网中的机器类型通信提出了一种新颖的中型访问控制（MAC）协议。被考虑的用例具有有限的地理区域和大量具有零星数据流量和不同优先级类型的设备。我们的目标是支持设备，同时使用单个访问点和单个渠道满足其服务质量（QoS）要求，这需要一种可以显着改善Mac性能的定制设计。在本文的第一部分中，我们提出了MAC协议，该协议包括一个新的插槽结构，相应的通道访问过程以及支持高设备密度并提供区分QoS的机制。该协议背后的一个关键思想是基于感知的分布式协调，以显着改善信道利用率。为了表征所提出的协议，我们根据设备的数据包到达率分析其延迟性能。分析结果提供了见解，并为第二部分中列出的QoS保证的细粒度调度奠定了基础。
In this two-part paper, we propose a novel medium access control (MAC) protocol for machine-type communications in the industrial internet of things. The considered use case features a limited geographical area and a massive number of devices with sporadic data traffic and different priority types. We target at supporting the devices while satisfying their quality of service (QoS) requirements with a single access point and a single channel, which necessitates a customized design that can significantly improve the MAC performance. In Part I of this paper, we present the MAC protocol that comprises a new slot structure, corresponding channel access procedure, and mechanisms for supporting high device density and providing differentiated QoS. A key idea behind this protocol is sensing-based distributed coordination for significantly improving channel utilization. To characterize the proposed protocol, we analyze its delay performance based on the packet arrival rates of devices. The analytical results provide insights and lay the groundwork for the fine-grained scheduling with QoS guarantee as presented in Part II.
