摘要
相比一般的嵌入式系统,无线传感器网络节点对操作系统的体积大小?能量利用率?节点相互间通信以及可重配置?可靠性和适应性等方面提出了更高的要求。由于这些特点,针对无线传感器网络节点也出现了各种各样的操作系统。阐述了无线传感器网络的特点及其对操作系统的要求,并介绍了当前无线传感器网络领域所应用的几种操作系统,提出了零操作系统的概念,也对传感器网络操作系统的版权进行了一些讨论,最后对传感器网络操作系统当前现状及发展作了总结。
Compared with the general embedded system, the operating system for wireless sensor networks （WSN） is more restrict in the aspects of code size, energy efficiency, network protocol, reconfiguration, reliability and adaption, et al. The characteristics of WSN and the demand of the operating systems are described. Several operating systems for WSN are introduced, and the concept of zero operating system is put forward. The license of open source operating system is discussed, and a conclusion to the present status and development of operating systems for WSN is made.
