Abstract: This paper provides a range-free localization algorithm——Midnormal-based Localization Algorithm(MBLA), which is based on midnormal. This localization scheme, which belongs to range-free localization algorithm, can save the energy caused by measuring range and can achieve good localization accuracy. By theory analysis and simulation, it shows that MBLA is better than APIT algorithm in localization accuracy and communication costs.

摘要： 基于区域位置估计方法，提出一种基于垂直平分线的定位算法——MBLA。该算法无需测距的定位，节约了由测距引起的能量开销，可获得较好的准确性。通过对MBLA算法与APIT算法的理论分析和仿真实验，证明MBLA算法在定位精度、通信开销方面的性能优于APIT定位算法。
