基于T i n y O S 的无线传感器网络体系结构





无线传感器网络WSN(Wireless Sensor Network) 由部署在监测区域内大量廉价的传感器节点组成,通过

无线通信方式形成multi2hop 自组织的网络系统,其目的是协作地感知、采集和处理网络覆盖区域中感知

对象的信息,并发送给观察者。本文从分析无线传感器节点Mica 和其上运行的操作系统TinyOS 出发,

着重描述无线传感器网络节点应用程序体系结构和消息通信机制。

-T iny OS-based wireless sensor network architecture, wireless sensor networks WSN (Wireless Sensor Network) deployed in the region to monitor a large number of low-cost sensor nodes through wireless communications multi2hop formed self-organized network system with the aim of collaboration to Perception, collection and processing network coverage area perceptual object information, and send observers. This article from the analysis of wireless sensor nodes Mica and its running on TinyOS operating system, the focus on wireless sensor network nodes to describe the application architecture and message communication mechanism.
