无线传感器网络室内定位系统的实现

Realization of Indoor Positioning System with Wireless Sensor Network

结合嵌入式操作系统TinyOS的通信机制,从定位数据收集和控制命令分发两个方面出发,利用无线传感器网络技术实现了基于接收信号强度的集中式室内定位系统,并考虑了不同定位算法的数据建模问题。最后以三边测量法为例在实际环境中对该系统进行了测试。

Combined with the communication mechanism of embedded operating system TinyOS, a centralized indoor posi- tioning system using wireless sensor network based on received signal strength is achieved from the aspects of positioning data collection and control command distribution. And data model- ing of different localization algorithms is taken into consider- ation. Finally trilateration is used as an example to test the positioning system.
