Abstract	Cyber-Physical Systems (CPS) are emerging as the underpinning technology for major industries in this century. Wide-area monitoring and control is an essential ingredient of CPS to ensure reliability and security. Traditionally, a hierarchical system has been used to monitor and control remote devices deployed in a large geographical region. However, a general consensus is that such a hierarchical system can be highly vulnerable to component (i.e., nodes and links) failures, calling for a $\textit{robust}$ and $\textit{cost-effective}$ communication system for CPS. To this end, we consider a $\textit{middleware}$ approach to leverage the existing commercial communication infrastructure (e.g., Internet and cellular networks) with abundant connectivity. In this approach, a natural question is how to use the middleware to cohesively "glue" the physical system and the commercial communication infrastructure together, in order to enhance robustness and cost-effectiveness. We tackle this problem while taking into consideration two different cases of middleware deployment: single-stage and multi-stage deployments. We design $\textit{offline}$ and $\textit{online}$ algorithms for these two cases, respectively. We show that the offline algorithm achieves the $\textit{best}$ possible approximation ratio while the online algorithm attains the $\textit{order-optimal}$ competitive ratio. We also demonstrate the performance of our proposed algorithms through simulations.
