摘 要: 设计并实现了一种无线室内定位系统,它基于一种混合接收信号强度指示器(received signal strength indicator,RSSI)位置指纹定位和惯性定位方法,同时提出一种动态活动区域聚类方法,以提高位置指纹法定位精度。实验结果表明,在室内环境下,相比于单独使用RSSI位置指纹定位,系统定位精度提高了35%以上。随着惯性传感器、无线通信芯片及体域网设备的普及,该系统在室内定位方面的应用很有前景。
关 键 词: 计算机网络;无线传感网络;室内定位;接收信号强度指示器位置指纹;惯性定位

Abstract: This paper designs and implements an enhanced indoor localization system which takes a hybrid approach with received signal strength indicator (RSSI) fingerprinting and inertial positioning method. At the same time, this paper also puts forward a dynamic activity area clustering method to improve the positioning accuracy of location fingerprinting. The experimental results show that performance of our system is increased by 35% compared to system only using RSSI fingerprinting. With the popularity of body area network devices with inertial sensors and wireless communication chips, we believe that this approach is very promising for personal indoor positioning system.
