A typical Internet-of-Things (IoT) system consists of three major layers: 1) sensing; 2) communication; and 3) application (i.e., actuation and control) layers. The co-design of these layers has been studied for over two decades, dating back to the concept of communication, computing, and control, i.e., 3C, convergence in the 1990s. Nowadays, with the emergence of wireless-networked machine-type applications, such as connected autonomous driving and factory automation, this co-design is more urgently desired than ever to meet the stringent quality-of-service requirements thereof. To realize this goal, the 5G wireless network of today has mainly focused on the communication part and strived to reliably achieve low air-interface communication delay, i.e., ultra-reliable and low-latency communications (uRLLC). However, more and more wireless communications in IoT are based on status updates instead of general content delivery. The current uRLLC design is insufficient to characterize the status update quality, and thus is unable to optimize for timely status update with constrained wireless resources. Therefore, the performance of computing and control in IoT networks that rely highly on wireless communications is suboptimal.

物联网传感、通信和控制协同设计的信息和数据语义时代的客座社论特刊

典型的物联网 (IoT) 系统由三个主要层组成：1) 传感；2) 沟通；和3）应用（即驱动和控制）层。这些层的协同设计已经研究了二十多年，可以追溯到 1990 年代的通信、计算和控制概念，即 3C 融合。如今，随着无线联网机器类应用的出现，例如联网自动驾驶和工厂自动化，这种协同设计比以往任何时候都更加迫切需要满足其严格的服务质量要求。为实现这一目标，当今的5G无线网络主要集中在通信部分，力求可靠地实现低空口通信延迟，即超可靠低时延通信（uRLLC）。然而，物联网中越来越多的无线通信基于状态更新而不是一般的内容交付。当前的 uRLLC 设计不足以表征状态更新质量，因此无法针对受限无线资源的及时状态更新进行优化。因此，高度依赖无线通信的物联网网络中的计算和控制性能并不理想。
