基于Tinyos的传感器网络程序实例开发

Tinyos操作系统采用的轻量级线程技术、两层调度方式、事件驱动模式、主动消息通信技术及组件化编程等有效地提高了传感器节点CPU的使用率,在Tinyos中采用NesC语言进行应用程序开发,有很多问题值得研究和探讨。从NesC语言基于组件化编程的特点入手,讨论基于Tinyos的应用程序的开发过程。分析了编程语言NesC的应用程序结构,结合实例给出完整的Tinyos中用Tossim模拟器模拟应用程序的过程,说明了应用程序开发的步骤及运行方法。

Research on Program Development Based on Tinyos in Wireless Sensor Networks

Tinyos operating system has effectively increased the CPU utilization rate of sensor nodes by using the lightweight thread technology, two-layer schedule mode, event-driven pattern, active message communication technology, component programming and so on. There are still many problems worth further research and discussion while developing applications based on NesC language in Tinyos. Starting from the characteristic of NesC based on component programming, the paper discusses the process of program development based on Tinyos, and analyses the structure of the programs based on programming language NesC. Combined with the piratical example, the paper finally gives a complete procedure simulating programs with Tissim simulator, which explains the development steps of the application and the way it works.
