Hussein El Ghor, El-hadi M. Aggoune . Real-time Operating System for Wireless Sensors powered by Renewable Energy Source. International Journal of Computer Applications. 81, 12 ( November 2013), 1-7. DOI=10.5120/14061-1961
Energy management is a central problem in real-time systems design, in particular for embedded wireless devices such as sensor devices. In our work, we aim at the improvement of real-time operating systems that are powered by renewable energy source (solar energy, for example). The objective of this work is to develop software components for the design of real-time operating systems. We provide an on-line scheduling scheme, named Earliest Deadline with energy guarantee (EDeg), in order to address the limitations in energy harvesting systems. We also integrate EDeg scheduling algorithm into CLEOPATRE open-source component library, a patch to Linux/RTAI and evaluate the scheduling overheads of EDeg observed under Linux/RTAI.
