基于WiFi的动态室内定位方法研究

Research on dynamic indoor positioning method based on WiFi

针对传统的室内定位算法难以有效解决节点动态移动对定位的影响问题,设计了一种基于优先级的动态跨层数据队列管理方法。分析了传统位置指纹的定位方法和容迟性问题,在数据链接层和MAC层之间实现优先级的数据队列管理机制,实验结果表明:融入该机制的室内定位比传统定位方法有更好的定位精度,数据传输率和自适应性。

Aiming at problem that traditional indoor positioning algorithm cannot eliminate impacts of nodes dynamically moving on position, design a dynamic cross-layer data queue management approach based on priority. Analyze on positioning method and delay tolerant issues of traditional location fingerprinting, and implement priority data queue management mechanism between data link layer and MAC layer. Experimental results show that the indoor positioning method which integrates this mechanisms has better positioning precision, data transmission rate and self-adaptivity than traditional positioning methods.
