The future wireless networks need to support the emergence of promising Internet-of-everything (IoE) applications, such as extended reality, automatic systems, and tactile Internet. These applications not only impose stringent requirements on the communication performance, but also require abundant computational resources for enabling fast and ubiquitous computing. This thus has motivated the development of new technologies to realize intelligent computing and communication to accommodate IoE applications. In particular, to overcome the limited computing power of edge devices, it is promising to smartly offload their computation-intensive tasks to the edge clouds that are close to the users, leading to the research area of mobile edge computing (MEC). Moreover, intelligent reflecting surface (IRS) can be utilized to smartly reconfigure the radio propagation environment in favor of computation offloading as well as reshape the computation-load distribution over the network to achieve better usage of computational resources. In this talk, we will discuss a set of energy-efficient resource management for achieving ubiquitous computing environment in future wireless networks. Moreover, we will point out several important directions for future research.
