The Internet of Things (IoT) is an emerging paradigm that can provide services for mobile devices, machines, and users with various quality-of-service (QoS) requirements. It is considered to have a wide range of applications in industrial and civil fields, such as transparent factories, smart cities, power grids, and intelligent agriculture. Meanwhile, the sixth-generation (6G) communication system is designed to support ultra-dense users’ connectivity, multi-gigabits transmission rate, and high information privacy, which is able to provide a better platform for IoT applications. As a result, research into 6G-enabled IoT has begun in recent years, in order to expand future IoT functions and applications.

6G-enabled IoT can make a great contribution to society by providing and promoting intelligent services for human beings. However, how to design a reasonable network structure to efficiently realize smart interconnection and handle the huge amount of unstructured/semi-structured data generated by resource-constrained IoT users in 6G networks is an important issue to be solved. Along with the development of emerging technologies such as artificial intelligence (AI), how to organically integrate them into the framework of the 6G-enabled IoT and explore various practical applications in real life still requires large-scale research and exploration.

This Special Issue aims to provide a platform for academic researchers and industry professionals to report and discuss recent technology advances and future potential applications for 6G-enabled IoT. We welcome original research and review articles with a focus on addressing network framework design, system multivariate conformity evaluation analysis, 6G-enabled IoT application mining and expansion, and the integration of 6G-enabled IoT and emerging technologies.
