SNOS：一种传感器网络操作系统的设计与实现

SNOS：Design and Implementation of an Operating System for Wireless Sensor Networks

传感器网络是一种新型的网络信息系统，其独特的特点包括：它是一个自组织网络，其运行和应用服务以传感器数据及数据聚合为中心，中间结点与信息服务紧密融合等．这些特征为操作系统研究领域提出了新的课题．本文提出了一种传感器网络操作系统一SNOS（Sensor Network Operating System），该操作系统以满足传感器网络的特点和需求为目标设计完成．本文论述了SNOS系统的结构和设计，系统资源机制和运行管理机制，介绍了SNOS系统任务实现的模拟试验和系统原型在煤矿井下初步应用的情况，为传感器网络操作系统的设计研究提供了思路和参考．

Wireless sensor networks （WSNs）, as a new class of networked information system, have some unique characteristics. These characteristics present new challenges to the research of operating systems. SNOS （ Sensor Network Operating System） operating system for WSNs, proposed in this paper, is designed to aim at the characteristics and requirements of WSNs. This paper inlroduces the design and architecture of SNOS, system resource mechanism and execution management of SNOS. The paper also presents the simulation of task execution on SNOS and the test of SNOS prototype in coal mine. The design of SNOS offers new idea and referrence to the research of operating system for WSNs.
