无线传感器网络在室内的应用越来越广泛,然而相应的无线信道衰落模型的研究却尚未成熟.为此,针对典型的住宅和办公环境进行了无线传感器节点的信道传输衰落特性测试,并对测试数据进行了拟合和建模.拟合结果表明,在大尺度衰落的情况下,所提出的三阶多项式对数距离路径损耗模型能够更好地表征室内环境下的信道衰落情况,对研究室内无线传感器网络的关键技术具有重要的参考价值.
However, the research of the corresponding wireless channel fading model is not yet mature.Therefore, the channel transmission fading characteristics of wireless sensor nodes are tested for typical residential and office environments, and the testing of wireless sensor networks Data fitting and modeling.Fitting results show that in the case of large-scale decline, the proposed third-order polynomial logarithm distance path loss model can better characterize the indoor environment of channel fading, the study of indoor The key technology of wireless sensor network has important reference value.
