【摘要】：无线传感器网络中多数低功耗协议通过控制休眠时间来降低系统功耗,而网络系统的多样性使其难以准确预估路由节点的最佳休眠时间。为此,引入排队论模型对局部路由节点的最佳休眠时间进行预测,从而增强路由节点的低功耗性能。针对单路由节点的情况,根据排队论进行建模估算休眠时间,通过Zigbee技术搭建具体的无线传感器网络系统并由硬件控制路由节点的休眠。将该系统应用到茶山温湿度检测项目中,利用网关从Internet远程网页监测茶山温湿度。应用结果表明,该方法可有效降低系统功耗。
[Abstract]:Most low-power protocols in wireless sensor networks reduce power consumption by controlling sleep time, but the diversity of network systems makes it difficult to accurately predict the optimal sleep time of routing nodes. Therefore, the queuing theory model is introduced to predict the optimal sleep time of the local routing nodes, so as to enhance the low power performance of the routing nodes. In the case of single routing node, the sleep time is modeled and estimated according to queuing theory, and the specific wireless sensor network system is built by Zigbee technology, and the dormancy of routing node is controlled by hardware. The system is applied to the tea-mountain temperature and humidity detection project, and the gateway is used to monitor the temperature and humidity of the tea mountain from the Internet remote web page. The application results show that the proposed method can effectively reduce the power consumption of the system.
