Abstract

A cyber-physical system employs a tight combination of and coordination between computational, networking, and physical elements. Wireless sensor-actuator networks (WSANs) represent a new frontier of communication infrastructure for cyber-physical systems in many important application domains such as process control, smart manufacturing, and data center management. Sensing and control in these systems need to meet firm requirement on real-time end-to-end communication. WSANs face significant challenges that stem from the requirement on real-time communication and that on cyber-physical co-design due to close coupling between control and communication. In this talk, I will first present a new real-time wireless scheduling theory for fast real-time performance analysis of WSANs. For holistic optimization in wireless control systems under stringent resource constraints, I will also present a scheduling-control co-design approach that integrates real-time scheduling theory, wireless networking, and control in a unified framework. I will then present the design and implementation of a real-time WSAN for power management in enterprise data centers. I will conclude my talk with the future directions of my research on new networking platforms, real-time computing, and large-scale sensing and control for next generation cyber-physical systems.
