An Indoor Positioning Algorithm Based on RSSI with Path Loss and Noise

在无线领域,对目标定位跟踪算法的研究成为热点,目前已有多种目标定位跟踪算法被提出。基于接收信号强度指示(received dignal strength indicator,RSSI)的定位算法由于其有利于节点小型化、能够穿越障碍物等优点被广泛应用。但是基于RSSI定位算法容易受环境的影响。本文提出一种基于三边定位技术和RSSI融合的带路径损耗和噪声的改进型RSSI目标定位跟踪算法。通过系统仿真,得到了仿真误差在0.3732 m的平均误差值。

In the wireless field,the research on target positioning and tracking algorithms has become a hot spot,and a variety of target positioning and tracking algorithms have been proposed.Positioning algorithm based on received signal strength indicator(RSSI)is widely used due to its advantages in node miniaturization and ability to cross obstacles.However,the RSSI positioning algorithm is easily affected by the environment.An improved RSSI target positioning and tracking algorithm with path loss and noise based on the trilateral positioning technology and RSSI fusion was proposed.Through system simulation,the average error value of simulation error of 0.3732 m was obtained.
