摘要
针对无线传感网络中RSSI信号波动的问题,分析了环境因素对其的影响,在MICAz节点平台基础上,验证了距离、天线方位、节点高度和发射功率对信号产生的波动大小。通过对实验数据的处理,绘制出RSSI信号的波动曲线以及随各因素变化的拟合曲线。实验结果对基于RSSI的节点定位、跟踪方面的研究提供实践依据。
Aimed at the problem of received signal strength indicator fluctuation in wireless sensor networks(WSN),the impact of environmental factors was analyzed.The influence caused by factors that were distance,antenna orientation,node height and sending power were implemented on MICAz motes.The volatility curve and fitting curve changed with various factors of RSSI were drawn based on experimental data.Experimental results provide practical references for RSSI-based location and tracking research.
