Preliminaries

This chapter begins with a focused introduction to industrial edge computing systems, emphasizing optimization metrics. The design of appropriate optimization algorithms is crucial for IIoT applications to ensure their QoS, reliability, scalability, and deployability. Subsequently, the chapter presents several related works, discussing their technical coexistence issues. Understanding the limitations of existing work enables readers to comprehend the interactions and interference among components (such as devices and edge servers) in industrial edge computing systems. The chapter also discusses potential changes that could be incorporated into future versions of industrial edge computing systems. These changes are considered in the context of offloading in end devices, caching and migration in edge servers, and applications. This approach helps to understand how improvements can be made at different levels of the system.
