摘　　要：无线传感器网络节点极为有限的能耗和计算资源对操作系统提出了很高的挑战。文中在分析了几款常见节点操作系统特点的基础上,提出并设计了一种传感器网络操作系统MiniOS。该操作系统是一个多任务、基于优先级的分时调度的操作系统,最多支持16个并发进程。讨论了MiniOS的进程调度、内存管理、设备驱动等几个方面,并与已有操作系统进行了对比。Limited energy and computing resources of wireless sensor network node constitute a big challenge to the design of operating system. Based on analysis of several popular node operating systems a novel operating system known as MiniOS is proposed. The system, as a multi-task scheduling, priority-based and time-sharing micro- embedded system, supports up to 16 concurrent processes. Several aspects in design, including process scheduling, memory management, device drivers, are discussed in detail and its comparisons with existing systems also given.

关 键 词：操作系统 进程调度 内存分配 无线传感器网络
