A Logical Time-Triggered Distributed Computing Environment for Cyber-Physical Systems with V2X Wireless Communication

The paper presents a logical time-triggered distributed computing environment for cyber-physical systems utilizing V2X (Vehicle to Everything) wireless communication based on IEEE802.11p protocol. Logical time-triggered processing realizes real-time distributed computing equivalent to the time-triggered architecture without time synchronization. We have developed a real-time operating system emulator running on Linux, which manages tasks based on EDF (Earliest Deadline First) scheduling with logical deadlines. We have also developed distributed computing middleware that manages logical time and timestamped messages and communication software that supports IEEE802.11p. By using the distributed computing environment, logical time-triggered cyber-physical systems with IEEE802.11p wireless communication can be developed without considering either timestamps or logical time.
