摘要
常见的基于测距的定位算法有Min-Max定位算法、三边定位算法和最大似然法,在研究这三种定位算法的同时,重点分析了Min-Max定位算法,并对其在定位边界区域误差较大问题提出一种有效的解决办法,并通过仿真进行验证。对比Min-Max及其改进方法的仿真结果表明,改进方法能有效改善定位边缘区域的盲节点的定位精度。
Common range - based location algorithms have Min - Max algorithm, triangular positioning algorithm and max- imum likelihood method. These three positioning algorithms are studied, while focusing on the Min - Max positioning algo- rithm, and effective solutions to resolve the problem that the blind nodes around the edge of localizaton region have larger position error are proposed. The simulation result shows that the improved method can effectively improve the position accu- racy of blind nodes around the localization edge.
