无线传感器网络中的Sink节点是数据汇聚的中心,它与数据采集终端通过一个串行接口连接.为了实现Sink节点与数据采集终端的通信,利用CC2430芯片的数据传输原理,用nesC语言编写了一个TinyOS系统下的I/O控制程序,并给出在CC2340芯片上实现的结果,可用来控制对Sink节点的输入和输出.对该程序进行一定的扩展和改进便可以实现对Sink节点与节点通信和数据传输的控制.

In wireless sensor network(WSN),the Sink node is the data aggregation center connecting with data acquisition terminal through a serial port. An I/O control program running in TinyOS system was compiled by means of nesC language and data transmission principle of CC2430 chip to realize the communication between Sink node and data acquisition terminal. The result realized with CC2430 chip is offered in this paper. The program can be used to control the input and output of Sink node. If this programme is expanded and improved to a certain extent,it can realize the communication between Sink node and other nodes,as well as the control of data transmission.
