一种基于实时路径衰减指数的WSN定位方法

WSN Location Method Based on Real-time Path Loss Exponent

随着无线传感器网络的快速发展,无线传感器网络定位成为重要研究领域之一。本文根据无线传感器网络应用于室外恶劣天气环境下的特点和实际需求,提出一种基于RSSI实时路径衰减指数的无线传感器网络定位方法,并通过仿真和在公路环境下的试验,验证了该方法的可行性。

With the rapid development wireless sensor network,localization has become one of the most important field in wireless sensornetwork research. According to the characteristics and actual demand of wireless sensor network used in outdoor environment of badweather, this paper proposes an localization method based on RSSI real-time path loss exponent. The result of simulation and experimenton highway proves the method＇s feasibility.
