Real-Time Wireless Sensor-Actuator Networks for Cyber-Physical Systems

ABSTRACT

A cyber-physical system features a tight combination of and coordination between computational, networking, and physical elements. Wireless sensor-actuator networks (WSANs) represent a new frontier of communication technology for a large class of cyber-physical systems such as process control, smart manufacturing, and data center management. WSANs in these systems face significant challenges that stem from the stringent requirements on real-time communication between sensors and actuators. Moreover, the close coupling between control and communication motivates a cyber-physical co-design approach. This talk will present my research on wireless cyber-physical systems to address these challenges. I will first present a new real-time wireless scheduling theory for fast real-time performance analysis of WSANs. I will also describe a scheduling-control co-design approach that integrates control, wireless networking, and real-time scheduling theory for wireless control systems. 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 embedded computing, and large-scale sensing and control for next generation cyber-physical systems.

Bio: Abusayeed Saifullah is a PhD candidate in the Department of Computer Science and Engineering at Washington University in St Louis. Advised by Chenyang Lu, he is a member of the Cyber-Physical Systems Laboratory at Washington University. Abu's research primarily concerns cyber-physical systems with contributions spanning real-time systems, wireless sensor networks, embedded systems, and parallel and distributed computing. He received the Best Student Paper Awards at the 32nd IEEE Real-Time Systems Symposium (RTSS) and at the 5th International Symposium on Parallel and Distributed Processing and Applications (ISPA), and Best Paper Nomination at the 18th IEEE Real-Time and Embedded Technology and Applications Symposium (RTAS).
