%X <p>Considering the characteristics of predictability for cyber physical systems (CPS) and the requirement of secondary storage for node systems, a research was carried for the existing flash file and sensor node file systems. A new node file system for CPS was designed, adopting virtual sector mapping technology and cascading page log strategy to ensure predictability, and also optimizing the file structures and data operations to improve efficiency. Experiments on the flash simulator show that the system has stable performances of sequence input/output (I/O) and random I/O. And the system image keeps small that means it is suitable to deploy on resource-limited nodes.</p>
