中文摘要：

针对当前农业环境在线监测的需要，提出了温度、一种利用具有自组织特性的无线传感器网络（wireless sensor networks，WSN）对土地湿度和土壤的PH值等环境变量进行在线监测的方法。该方法采用了对等式网络体系结构、低功耗微小网络节点、基于拓扑树的网络初始化配置算法．实验测试表明节点能够有效地采集和处理数据，并可以在节点间成功地进行通信。

英文摘要：

With the requirement of agricultural environmental conservation and monitor, a wireless sensor networks based online monitor method is proposed for the temperature, humidity network architecture, low power node design of system layer and topology tree and based PH value. The peer-to-peer network initialzation and configuration process are adopted in this system. The experiments indicate that the nodes can gather and process data effectively and communicate between the nodes successfully
