The goal of this thesis is to give a scheme on the application of wireless sensor network system indoor . first of all , we have a deep research on the ‘ telos ’ node , secondly , we build up a stack system structure of wireless sensor network to monitor the temperature of the building intellectively , design and realize the network stack including physical layer , data link layer , network layer and application layer . finally , we debug the software in order to verify the network layer and the application layer 本文以智能楼宇温度监测应用为设计目标,以em2420射频芯片和atme128l单片机为设计载体,在详细研究telos节点方案基础上,对面向设计目标的室内无线传感器网络节点的物理层、数据链路层、网络层和应用层之间的网络协议栈进行了实现性设计,建立了立足设计目标的无线传感器网络协议体系,并在avrstudio4 . 11调试环境下对网络层和应用层设计正确性进行了调试验证。
