Schedule mechanism of TinyOS and its real-time schedule component design

TinyOS is an open-source component operating system for sensor networks nodes that has very limited resources.TinyOS was implemented in component-developing language nesC.Through analyzing the schedule mechanism of TinyOS-2.x,a soft real-time scheduler component was designed and implemented for real-time applications.Simulation results in TOSSIM demonstrate that the soft real-time component improves the real-time performance of TinyOS.
