摘要
在对无线传感器网络体系结构、传感器节点、网关(Sink)节点的特点和功能分析的基础上,给出了传感器节点和网关(Sink)节点的软硬件设计与实现方案。在软件设计方面深入研究了嵌入式实时操作系统uC/OS-Ⅱ的特点和内核结构,实现了uC/OS-Ⅱ在Nios处理器上的移植。同时介绍了小型TCP/IP协议栈LwIP以及LwIP在uC/OS-Ⅱ上的实现。
Design and realization scheme of sensor-node and sink-node in soft and hard were proposed based on the introduction of its system structure, characteirstics and function. This papers deeply researched characteirstics and kernel of the embedded RTOS uC/OS-Ⅱ, and transported the uC/OS-Ⅱ successfully to the controller Nios. The mini type TCP/IP protocol stack LwIP Realization of LwIP on uC/OS-Ⅱ was introduced.
