Abstract
Flash equipped sensor devices are becoming increasingly complex and are now capable of supporting real-time multiple applications on a single sensor, rich sensing of visual and audio data, and storage of large amounts of data. With this increase in complexity, it is no longer sufficient to provide first in first out (FIFO) type capture of data into more persistent memories. In this paper we propose RG-EDF, a new scheduling policy for flash equipped sensor devices. RG-EDF aims at providing QoS support to multimedia tasks by considering the unique characteristics of flash-based devices. We have implemented our scheme on a CC1010 sensor node with a SD flash card attached and compared our technique to other popular scheduling policies. Our experimental results show the working and benefit of our system. © 2008 Springer-Verlag Berlin Heidelberg.
