| Abstract: | Being aimed at wireless sensor networks nodes multitasking and energy-sensitive features, a real-time operating system based on event-driven is proposed for embedded application. A thought of hierarchical structure is adopted to build the modular system components. Simple and effective memory management is achieved using the memory control block list. The low power consumption and preemptive task scheduling is implemented based on event-driven and task priorities. The experimental result shows that the system has low power consumption and good real-time quality. |
