Abstract: Cyber-Physical Systems (CPS) increasingly rely on decentralized and dispersed computing to operate effectively in distributed and heterogeneous environments. Decentralized computing enables operation across trust boundaries, while dispersed computing facilitates efficient workload distribution across networked edge and cloud resources.

I will discuss recent research on these paradigms in the context of CPS. Topics include Byzantine fault-tolerant consensus for resource-constrained environments, decentralized publish-subscribe systems, and smart contract mechanisms for secure peer-to-peer transactions. Additionally, we will examine the role of decentralized data marketplaces in enabling secure and efficient data exchange for CPS applications. On the dispersed computing front, we will explore workload orchestration across diverse computing resources, graph-based scheduling techniques for optimizing task placement, and parametric approaches to task graph scheduling.
