摘要
针对稻田环境特点与网络可靠性需求,在理论分析和实地测试全向天线和定向天线无线信号传输距离的基础上,设计了基于混合天线WSN分簇组网模型,分析其网络运行机制。经实地测试,与全向天线组网方法相比,混合天线WSN网络中簇头节点的寿命提高近45%,从而有效地提高了整个网络的存活时间。
According to the characteristics of the paddy field environment and network reliability requirements, on the basis of theoretical analyzing and field testing the wireless signal transmission distance of the omni-directional antennas and directional antenna, a hybrid antenna WSN clustering network model was designed,and its network operating mechanism was analyzed. By the field test,compared with the omni-directional antenna networking method, the life of cluster head nodes in hybrid antenna WSN network increased by nearly 45%,which could effectively improve the survival time of the entire network.
