With the widespread proliferation of intelligent terminal devices across global networks, the effective integration and utilization of dispersed terminal device resources has emerged as a critical research focus. The prolonged idleness of terminal computing power is a significant issue that needs to be addressed. Terminal computing power networks offer a promising solution by centralizing the management and scheduling of terminal device resources distributed across various locations, thereby forming a large-scale distributed computing network and significantly enhancing resource utilization efficiency. This article aims to provide an in-depth analysis of the current research status and characteristics of terminal computing power networks. We propose a functional logic architecture for terminal computing power networks and explore the key technologies that will drive their development. These key technologies include resource perception, resource prediction, application deployment, and load balancing within terminal computing power networks. Our goal is to lay a solid research foundation for future investigations and applications in this field.
