PROJECT TITLE :

Robust and Cost-Effective Design of Cyber-Physical Systems: An Optimal Middleware Deployment Approach

ABSTRACT:

Cyber-Physical Systems (CPS) are emerging as the underpinning technology for major industries in this century. Wide-area monitoring and control is a vital ingredient of CPS to make sure reliability and security. Traditionally, a hierarchical system has been used to monitor and control remote devices deployed in a large nation-state. However, a general consensus is that such a hierarchical system can be highly susceptible to element (i.e., nodes and links) failures, calling for a robust and price-effective Communication system for CPS. To this end, we have a tendency to consider a middleware approach to leverage the prevailing commercial communication infrastructure (e.g., Web and cellular networks) with abundant connectivity. During this approach, a natural question is how to use the middleware to cohesively “glue” the physical system and also the commercial communication infrastructure along, so as to boost robustness and value-effectiveness. We tend to tackle this problem while taking into thought 2 different cases of middleware deployment: single-stage and multi-stage deployments. We style offline and on-line algorithms for these 2 cases, respectively. We have a tendency to show that the offline algorithm achieves the most effective potential approximation ratio whereas the online algorithm attains the order-optimal competitive ratio. We conjointly demonstrate the performance of our proposed algorithms through simulations.
