Recent Progress on Security-Communication-Computing-Control Co-Optimization for Industrial Internet

The blockchain-empowered end-edge collaborative computing network is considered a promising network paradigm in the Industrial Internet, providing a secure and efficient scheduling framework. Nevertheless, the diversity of task requirements and the complexity of blockchain mechanisms have led to poor performance of this framework. Therefore, this article provides a categorized literature review of existing works on a security-communication-computing-control (S3C) co-optimization strategy based on blockchain-empowered end-edge collaborative computing intelligent scheduling frameworks and analyzes them from the perspective of the evolution of optimization algorithms from non-learning to learning-based algorithms. Furthermore, we identify key challenges for future research and summarize potential future research directions.
