。通过对传统定位算法原理和误差来源进行分析，结合贝叶斯滤波概率模型对Euclidean定位算法进行

改进，使接收信号强度指示器随机波动得到有效的抑制。-. By traditional positioning algorithm principle and source of error analysis, probability model with Bayesian filtering algorithms to improve positioning of the Euclidean, so that random fluctuations in received signal strength indicator is effectively suppressed.
