摘要
分析了以接收信号强度为基础的三边测量法和场景分析法两类无线室内定位算法的基本原理,利用无线传感器网络节点在实际的室内环境中对这两类算法进行了测试并对它们的定位精度进行了分析和对比。
We analyze the basic principle of two types of received signal strength based wireless indoor positioning algorithms,which are trilateration and scene analysis.Then these two algorithms are tested in real indoor environment with wireless sensor nodes and their positioning accuracies are analyzed and compared.
