A file system for system programming in ubiquitous computing
Tóm tắt
In Ubiquitous computing, small embedded sensor and computing nodes are the main enabling technologies. System programming for such small embedded systems is a challenging task involving various hardware components with different characteristics. This paper presents a file system which organizes all computational and sensory functionality of a sensor node as resources in a uniform name space. It further provides a lightweight and uniform access model for all these resources. This mechanism forms an abstraction from different hardware, makes functions re-useable and simplifies the development on such systems. With ParticleFS a concrete file system implementation on a sensor node platform is shown. Application cases demonstrate sensor logging, an interactive shell, executables, a pipe mechanism and remote access capabilities of the ParticleFS.
